Quoting Normie999 (Reply 283): Back in the day, a zillion entries ago, I speculated about Air France's "excellent safety record" (entry 6 at - AF A332 Crash (F-GZCP) Part 14 (by Moderators Jun 8 2009 in Civil Aviation)).
Well, two weeks on, fingers are being pointed every which way - the AF crew, faulty speed dials, weather updraft, weather downdraft, non ferrous panels, fly-by-wire, Airbus manufacturing techniques, etc etc, but not a lot at AF itself.
I'm not sure why not. There is a bit of history here - Concorde at CDG, Toronto, icing problems, and a propos F-GZCP, Airbus sent out a service bulletin in late 2007 advising the replacement of some probes, which Air France did not fit.
The article I quoted from was speculative, but it seemed well-informed, and raised questions about AF that don't yet seemed to have been addressed much.
Well, I am sorry to say, that like so many you are making suggestions and trying to implicate way too early. Please try and stick the the data and facts we have. Facts are great, but trying to draw conclusions from facts is dangerous until we know ALL the facts and information in relation to this tragedy
Where's the passion gone out of the airline industry? The smell of jetfuel and the romance of taking a flight....

Quoting Speedbird128 (Reply 282): As a radar and non-radar controller, it does matter to me if there is track deviation. It *can* affect the longitudinal time separation if the aircraft behind at the same level doesn't deviate off track too, and also, it may interfere with assumed lateral separation from other airways (they may also have traffic deviating).
That's why the controllers are mainly interested in your ETA and ATA. If the route is in proximity to other routes and both routes are dense... well, you're better off telling someone about it. Who knows, someone near might be having TCAS / ModeC problems.
They might not have been able to raise ATC due to the weather conditions too at the time of AF447, VHF should be OK, but I doubt HF would be clear.
One thing is AF447 was coming up to enter Dakar FIR, as far as we know, they never managed to contact Dakar am i correct? (I think they use the "at least 15 mins prior to entry", on HF given the distance and weather).
By the way, whatever happened to "standard airway offset" method to reduce collision risk?
--------------
Sorry, I just can't let go of that "error" for knowingly flying into bad weather... *bangs head on table* Let me add to the above post on clouds and radar... What do they get on the planning stage? Apart from Wind charts (which doesn't show turbulence), they get the SigWX (significant weather), and Weather Satellite picture...
OK... on the following charts, the Atlantic between Africa and Brazil isn't so bad today... but then...
Weather Satellite Pic:
SigWX chart...
Look at the SigWX (significant weather) chart and see L (Lagos)... nice big swath of CB clouds... and look at the Satellite pic... nice solid cloud cover...
I guess we should all cancel our flights to/from/over Lagos today shall we?
*bangs head on table*
Wait wait... That says ISOL EMBD CB 500 XXX
Isolated Embedded Cumulonimbus Clouds ground to FL500...
Some might say, see, it's only ISOLATED... it's not really bad... if it's worse... they would have deviated and/or cancelled flights...
What's worse? Above ISOL, then we have OCNL... Occasional...
Then why not see this?
We got this... taken during one monsoon season...
The flight path is shown... Oh no... it went through the bad parts...
The aircraft was an A330, flying at FL360... it survived... It was damn bumpy, not a lot if deviations were required... and the OCNL CB parts was solid white on the Infra Red weather satellite pic... and everyone prayed during the flight (it was a Hajj flight), and the plane traversed through the bad weather later on the way back... and again and again... everyday throughout the Hajj season during the monsoon.
They (pilots), do this everyday! The aircraft survived.
Why did I pick these examples and why are they relevant to AF447? It just shows that facing the weather and having to go through these so called "solid patches of white" is an everyday occurence. Whilst increased vigilance and awareness during the flight is called for, it's not something you'd spend tens of tons of fuel a flight to avoid... and the intensity of the clouds along the route of AF447, isn't anything out of the ordinary. What may be out of the ordinary, was the rapid change in temperature at FL350, which cannot be accurately predicted beforehand, and nothing in the aircraft can predict such a change.
By the way, don't be surprised to see nothing but red cruising around Lagos tonight...
Anyone got the SigWX chart for the Africa-Brazil crossing for that night?

It seems like whenever a new fact, fragment of debris or piece of information comes out, we're not taking things at face value, instead reading too much into them. Information is coming so slowly, and we're understandably anxious. This is not what people like to hear but we don't know much, and will not know a whole lot for a while apparently.
At work I am the local aviation nut, and everyday I run into people asking me: so what happened to the Air France flight? Frustrating as it is, I honestly have to say that things start pointing to an inflight breakup, but beyond that we don't really know anything.

Does anyone know if the A330-xxx has variable ratio or variable stop rudder control systems? This presents an interesting scenario correlation to AA578 especially given potentially inaccurate airspeed indications. Additionally, did PF have acrobatic experience? That would say a lot about potential rudder inputs in severe turblence. Given the combination of significant turbulence, inaccurate airspeed data and the effect of same on variable rudder control systems, and composite materials leads to an interesting scenario.

Quoting Mandala499 (Reply 2): It just shows that facing the weather and having to go through these so called "solid patches of white" is an everyday occurence.
Nicely put Mandala. Allow me one question. What kind of images of tropical intense weather (like monsoons) over the equator area should an on board weather radar depict in order for a cockpit crew, beginning to make the crossing, to decide to turn back and land in lets say Recife. I doubt very much if such a case occurs frequently. Please exclude cases of hurricanes, cyclones, typhoons etc.
Why get so offended by the scenario of "error in picking up the wrong way while playing hide-and-seek with the thunderstorms"? It depends on one's point of view. You may call it very very bad luck (once every x millions of flights), someone else may call it human error. Errors, even the most costly, are for human beings. Many accidents in aviation are one of a kind and have brought major changes after their occurance and many people dying. Maybe that will prove a rare accident having a sole cause : severe weather causing plane disintegration. You can then blame weather for becoming more unperdictable because of global warming? pilots for underestimating the intensity of weather? It is up to you to choose.
Generally speaking (and not in connection to the terrible accident), sometimes such an error can derive from human ego and persistance to manage to make it through the bad weather and achieve a target (reach a destination) on time (it has happened before in aviation and happens in all aspects of a man's routine for example in driving one's car - that obsession one often has to fininish some task one way or another). Otherwise it could mean humiliation and bring critisism by co-workers. Sometimes airliners' policies put great deals of pressure on pilots to be careful with fuel consumption (especially in our times of tight budgets) and to be punctual to the minute with timetables (because of intense competition).

Answer : NONE . Your persistence in trying to prove your case is based on very little knowledge of airliners operations / We just don't happen on an unexpected situation like this one ; we have a flight preparation before departure, at which we are provided with all the weather information available : Synoptic charts, surface chart, altitude charts at 850, 700, 500, 300 &nd 200 HPa, crew weather reports and satellite pictures, both for sit and infra red. Plus a telephone link with a dispatcher who can slice up the sat picture to give us the best levels for turbulence...etc....etc... It's only after that analysis that we accept or not the planned route, chose the fuel uplift and basically deal with the Tec and Nav aspects of the planning.
In cases of really severe weather like cyclones and tornadoes, the dispatchers would prepare for some deviations to the stored routes, the minimum being 200 Nm from the depression, deviation that has to be flight-planned, giving an even wider margin to the phenomenon as it must respect established routes and waypoints.
AF crews in particular are well aware of the particularities of tropical weather, first by going through a thorough course on the subject, secondly by experience accumulated over 85 years or so. (We opened the South Atlantic route for the Europeans with the Germans).
We have now two studies on the weather situation at the time AF 447 crossed the ITCZ, one by Tim Vasquez, the other by the METEOFRANCE engineers (found on the BEA site which I cited some 300 posts ago). Both agreed that there was nothing out of the ordinary in the situation, MeteoFrance stressing the fact that the Cbs had started their decaying phase at 0200Z, which Tim just gives a passing comment.
On Tim's study, the reconstituted radar picture, correlated with the Sat picture also shows that even if they hadn't deviated, they would have cleared the red spots of the active Cbs by a wide margin.
So, now, why don't you really tell what your gripe is about and what your agenda is ? I am personally interested. As for your claims that you do it in order to further flight safety, your knowledge of this subject is appallingly very selective.
Now for the so-called 200 Nm deviation by the following aircraft. Some posters have said that they saw AF 447 going straight into the storm, that they saw them as a TCAS target at 80 Nm, and then they deviated to the left... Fine...a/ that would have put them about smack over the "cold spots" Tim shows in his Fig 6, and b/ that would have necessitated a track correction of some 70 degrees. Wow ! Wonder what ATC and the aircraft in the vicinity thought of that !

Quoting Giopan1975 (Reply 265): Errors, even the most costly, are for human beings.
True, Giopan1975. And you can have your opinion, without any doubt. But aircraft are built by people, too. As is the equipment. So are weather forecasts. Need more?
You created a crystal ball theory and I am happy to show you what I mean with that:
1)
Quoting Giopan1975 (Reply 265): I donât see any reason why cockpit crews cannot be blamed for anything (even at this stage of the investigation and being totally speculative with very little evidence at hand) since pilot error is clearly top of the list of aviation accident causes.
Fine, you are suggesting crew error could have contributed to the accident and you point to historical evidence. Nothing wrong with that, except that, at this point, historical information is completely unrelated to this specific accident.
2)
Quoting Giopan1975 (Reply 265): ...they would deviate this kind of thunderstorm activity and the fact of other planes rerouting during the same night, I think we could reach some still unsafe but conclusion.
Pure speculation.
3)
Quoting Giopan1975 (Reply 265): ...that the aircraft should have never been caught in that area of severe weather activity in the first place.
Wild speculation unless you had a personal tracking device installed on the plane.
4)
Quoting Giopan1975 (Reply 265): So, probable cause (together with or among others?) that plane was flying in severe weather.
This is speculation based on more speculation - other sources suggest the weather wasn't all that bad at all. Now you're combining several speculative assumptions to create a 'probable' cause.
5)
Quoting Giopan1975 (Reply 265): Of course one may try to find as many excuses as one likes (unreliable weather radar, very fast and not easily predictable developing weather systems etc).
Well, pointing the finger (quoting you again) is certainly easier, sir, isn't it? That alleviates the necessity to confine yourself to the facts. What a convenient way of reaching a conclusion.
So, at least in my view, what the problem with your remarks is, is that you combine too many assumptions as you try to establish cause and effect. Understandably, this creates a lot of frustration in the minds of those who have been trying to avoid that over the cause of the last 5,000 (!) posts.
I hope you understand what I am getting at. I'm not attacking you personally, just trying to set this straight. Of course, everyone's entitled to opinion.

I haven't read that anywhere. Instead, I read a few reports quoting the deviation of IB6024 as 30 nm in some places, 60 km in others. This is one example:
On that night I was flying TP168, GIG-LIS. The plane left GIG about 75 minutes prior to AF447. We only experienced light turbulence, about which the captain warned us before taking off. We didn't seem to deviate from the standard path that I have taken in other trips from GIG to Europe, although I realize this is a rather imprecise statement.

Sorry to disagree but I don't think you're totally correct : Most people only see what they want to see and nowadays, it's trying to prove in-flight disintegration or ground impact.
There are lots of more important aspects that we could concentrate on :
Examples
1/- There are now two pieces that we can identify as parts of the crew rest container : They have been found on separate occasions, but how far from each other ?
2/- The crew jump seats, now identified as the L1 door, the senior purser position, associated with the doctor's kit, also in the forward part of the cabin. Where were they found ?
3/- The left #1 spoiler... Did the tanker find it in a totally remote area or were there some other debris with it floating alongside? what could cause the kind of breakage that we can observe ?
4/- The bodies, when identified, were they found in groups as they were in their official seating ? or did they belong to all classes of the cabin? (That answer will have to wait at least two months)
5/- The ACARS messages that everybody has forgotten about : How to make sense with them ? What are they indicative of ? Can we accept their order of reception by the maintenance computer ?...
By asking that kind of questions, and only that way, we could escape the trap of the "pet theories" and come closer to an understanding of what could have happened. But, of course, we'll know everything when the investigation report is published.
I' not sure we could wait that long.

Thank you, UALWN.
That's what I could remember, too.
Please note that their course alteration to the east as reported would have taken in the same situation as pictured by Tim.
Which tends to prove that radar interpretation can lead to many different decisions.

Well, I'm afraid that what's left. I've read most of the posts since the accident and have participate in almost every thread, mainly by asking questions. There has been many qualified insights, though some are too technical for my (very small...) knowledge. I believe a great deal of this accident threads as to do with some cathartic effect we all seek to overcome these tragedies, and sometimes people go a bit out of line. The topic is cooling down, which is a good thing. It still puzzles me that the definitive reports take so long, not obviously in the present case, but in others that apparently were more simple. I guess the speediness of today's world contaminates everything...
I would like to thank Mandala449 for all his excellent post on various issues. Thank you for educating the non-pilots among us...
At the end of thread 16 there was unfortunately a discussion about pilot error - as if the pilot making what turns out to be a wrong decision is automatically a case of pilot error.
Another did mention that pilot error is the last thing looked at by the root cause team.
I'd like to expand on that: I am a root cause evaluator in the Nuclear Power industry. Aerospace, Medical, and Nuclear all use the same process (and consult the same industry expert consultants to assist on any truly big event).
Right now we only have a few facts and a limited timeline. Before the root cause investigation can begine to narrow down the cause of the event there will be hundreds - if not thousands - of individual facts. Only then by assembling all of these individual facts and building a timeline can a pattern appear that leads to a root cause - or accasionally several root causes.
We are taught that in Root Cause analysis that actual human actions are virtually never the root cause. In the many years I have been involved with nuclear plant root causes (we do them on any major unexpected upset of the plant, any near miss, any major process problem, etc.) I only know of one root cause analysis where the conclusion pointed to "operator" error/intentional actions. In my discussions with industry peers it seems that this only comes up once in a while.
Now that does not mean that someone did not in fact do something that caused the event. The key is that we look for why that person did what they did.
Was it improper training... Then the root cause is a weakness in the training program; and we perform better training.
Was it an improper procedure... then the root cause digs into why the procedure was wrong?
Was it that a supervisor or manager was standing over their shoulder telling & intimidating them that they will do what they want or they will be "in trouble" (a very quick career ending move for the supervisor or manager - they will never get a job in the nuclear industry again); or perhaps just distracting the operator from their job.
The list goes on and on; including the fact that at times people face situations where they have not been trained on how to recognize what is going on and/or how to properly respond as the situation is very rare.
In fact - more often we come to a conclusion that we cannot identify a root cause than we identify that it was just "operator" error. There are of course casual contributing factors that are always identified.
Now I admit that an airplane is in a bit different situation as a pilot does not have multiple people they can check with for any given situation like exist in a nuke plant. However, in the end the pilot, copilot, and other crew must make a decision (and not making a decision is a decision as well) - and they make the best one they know how based on their training, experience, etc.
Even if it is the "wrong" decision and it causes the event - that does not necessarily mean it was "pilot/operator" error.
This does not mean that pilot error (or intentional actions) does not occur. Just that the conclusion to reach that point has to consider and eliminate all of the factors that could lead a person to making a wrong decision - and then ask: should the person have really known what to do.
I would hope that there are a few pilots on this board who have participated in a Root Cause Evaluation. It takes at least a month to be involved even in a small part of such an investigation - but going through the process is very educational.
As far as this crash: we may never know what the cause of it was. In fact â even if we recover the CVR and FDR we may never know the cause.
Meanwhile â I will track the few facts we do know â and watch for others to see where it could go. Until then there are dozens of possible causes and as long of list of more improbably causes (meteorites/space junk, aliens, monsters from the deep, etc).

If you look at some of the better images of the vertical stabilizer, you can see parts of the fuselage are still bolted to the vertical stabilizer. In the AA crash one of the four bolts of VS was ripped off and thus resulted in the failure of the vertical stabilizer. But here you can see the bolts are still there. If anything the forces were such that the vertical stabilizer ripped out a piece of the rear fuselage. And that's unlikely to be the cause of the crash but rather a consequence of the crash.

If you use the word error, it's much milder than:

Blame and error are 2 different things... Blame/culpability/liability, belongs in the courtroom. Error is the normative word for indicating a mistake for accident investigation purposes... even when coming accross willful misconduct.
One cannot point the finger of blame with this scarce amount of information. When the information is "adequate", and after the accident investigation is over, then the lawyers and judges can start their own work.
Pointing the blame finger at this stage, does nothing to improve safety and does nothing to prevent future loss of life. As for criminal liability, there is also a huge debate on its purpose and detrimental effect to safety in general. I'll leave the discussions on criminalisation of accidents for a separate topic... please!
I do hope you understand the above... we're not asking for you to agree to it.
Let's get on with the subject in hand, the accident.
Quoting Giopan1975 (Reply 6): What kind of images of tropical intense weather (like monsoons) over the equator area should an on board weather radar depict in order for a cockpit crew, beginning to make the crossing, to decide to turn back and land in lets say Recife. I doubt very much if such a case occurs frequently. Please exclude cases of hurricanes, cyclones, typhoons etc.
Black patches/wedges of black with red borders (no intermediate yellows and/or green between the red and the black)... That's a no-no for everyone on a revenue flight... doesn't matter if you possess 1hr, 50hrs, 500hrs, 5000hrs or 30,000hrs in your log book, it's a no-no.
Apart from that... there really is no defined limits. It's like asking, "how do you go across a moving crowd?" The answer is... there's no set path. One has to rely on one's training, systems understanding, meteo understanding, and experience (one's own, or from others).
Your doubt in the frequency of turning back is justified... on very few occasions would you then say, "oh-oh, this is too much, let's turn back" (unless you see those blackholes on the radar, you just avoid them).
A wide consistent blanket of red isn't avoidable sometimes. You can play the gain dial to see if you can get an uncalibrated picture by shifting the intensity readouts... but you have to know what you're doing. In the God knows how many flights I've done in my life (not too many, but not a few), I've only been in a situation of making that 180 turn once... I was a passenger, but can see the solid wall of a series of CBs ahead, left, and right... we didn't divert, we just went around the dead-end and found another gap... a big gap in fact. It was dusk... so there was some light.
A blanket of red can mean... dense consistent rain (heck, just go through it), or dense rain with several CBs there (rare, but it happens). A lot of the time, you'll get a blanket of green/yellows and the patches of red which are potential CBs... Now when you can see an anvil, you don't bang your head into it... The problem is... it does not have to be red to signify an anvil. You can have a CB of green... Normally, one would expect the CBs to be a patch of red. Whats dangerous about a CB is not always the amount of precipitation, but the updrafts and downdrafts associated with it, and it doesn't have to be a huge one or a red one to rip your plane apart, or give you a roller coaster ride nearby it, or give you a hailstorm near it or... give you icing...
The solution against this isn't easy. If you make the radars more powerful, you risk loosing accuracy... technology can sort that as time goes by, but you have to make it safe. You don't want to fry, or microwave someone or sterilize someone's reproductive organs from accidentally beaming the radar onto them whilst on the ground. The radars are afterall, electromagnetic radiation transmitters.
Whilst saying turning back to Recife is easy because this plane didn't and ended up in the sea in pieces, the question remains, did the crew see what was ahead? The thing is, you can be between patches of cloud and get icing. AF447 is strongly suspected to be brought to a haywire 4 minutes because of it prior to its demise.
There are reports suggesting that a rapid change in temperature occured which can cause rapid and excessive icing. This is probably what occured during Air Caraibe's similar episode. Unfortunately, planes aren't equipped to see what temperatures lie ahead. If the same happened to AF447, we want to know why Air Caraibes made it through and AF447 didn't... so we can better prepare flight crews the next time this happens to them should they enter such an unfortunate situation.
Turning back is the easy way out, but remember, airlines are there to carry passengers from A to B safely and in a timely manner... but they still have to get the passengers from A to B. We can all sit here and talk about safety, thanks to the benefit of hindsight, we can say, they should have turned back... but then, what would the passengers think?
This is the irony of air safety... airlines can be blamed for saving people's lifes!
Q: "Why did we divert to Recife?"
A: "The weather was bad, so we diverted for your safety!"
Q: "But the other Air France flight made it, the Iberia flight made it, why not us? You're lousy! I'm flying someone next time!"
As crazy as it sounds, those responses aren't abnormal. There is that difficult balance crews and the airline has to consider... talk about trying to reach zero accidents as an absolute goal are mere rubbish... But carelessness or gross negligence isn't the way to go either... have too many accidents and the passengers will fly with someone else. Have too many delays and diversions when others aren't doing the same, and the passengers will fly with someone else.
Making those judgement calls on whether to continue or not (and how to deal with a mishap onboard), is why crews get paid... an unlicensed person can fly the plane from A to B on a good day, the technology exist to support that, to the extent that on good days, you don't need the crew at all and just leave it for the automation to take care of it... But again, who's going to make the judgement call in difficult circumstances? A machine or a human? As imperfect humans are, I'd choose the humans and not the machine, because machines are designed by humans. Nuff said!
There is no doubt that an error occured during AF447... be it technical or human... but I do hope you understand that apportioning blame so early is counter productive to the future of air safety!
Quoting Giopan1975 (Reply 6): Generally speaking (and not in connection to the terrible accident), sometimes such an error can derive from human ego and persistance to manage to make it through the bad weather and achieve a target (reach a destination) on time (it has happened before in aviation and happens in all aspects of a man's routine for example in driving one's car - that obsession one often has to fininish some task one way or another). Otherwise it could mean humiliation and bring critisism by co-workers. Sometimes airliners' policies put great deals of pressure on pilots to be careful with fuel consumption (especially in our times of tight budgets) and to be punctual to the minute with timetables (because of intense competition).
If you want to talk about human error and ego as a factor in this accident, then let's try and find out more. You don't get that by stating there's undoubtedly blame on the crew... Let's find out what happened first, and we'll play the blaming game later if needed!
---
What do pilots get in the pre-flight stage with regards to the route? Let me elaborate what Pihero mentioned... so as to appreciate the amount of information provided prior to the flight.
- Flight details.
- Aircraft capability and maintenance status details.
- The route itself (routing).
- What's in the aircraft (weights)
- What's the minimum required fuel, what's the recommended fuel given the conditions, and what extra fuel the crew wants.
- What are they waypoints, and when is the expected arrival times at those - waypoints based on flightplan, what height, what speed.
- What are the forecasted wind and temperature at those waypoints.
- Route plots, and range circles to suitable contingency diversionary airfields, including origin and destinations.
- Information of the airfields, weather reports actual and forecasted for those airfields, and notams on those airfields, and areas.
- Any significant meteorological information that can affect the flight... hurricanes, or volcano ash.
- Any Notices to airplanes and air crew (NOTAMs) that can affect the flight.
- Significant Weather report and data and forecasts.
- Wind and temperature charts.
- Technical bulletins, notices and advisories.

Quoting Pihero (Reply 9): Your persistence in trying to prove your case.....
There is no case I am trying to prove, just trying to see things from different angles. And there is no scenario (from the ones that have been heavily discussed) that can be dismissed so far.
You are doing nothing more than I do and that is pure speculation. Our only difference is my very little knowledge on airlines operations vs you being a pro. The rest is called speculation - doesnt matter if it comes from a pilot or a passenger. Your point that weather was nothing special and another day at the office for the french crew is very very possible and totally acceptable but still no concrete evidence to support it 100% unless you know something the rest of the world doesnt. Tim's study may be great but cannon be conclusive of anything. His own words. "Of course anything so far is speculation until more evidence comes in, and for all we know the cause of the downing could have been anything from turbulence to coincidental problems like a cargo fire. " How can you be so sure that some exceptional weather phenomena did not occur at a teribbly unlucky time sequence?
Quoting Pihero (Reply 9): So, now, why don't you really tell what your gripe is about and what your agenda is ? I am personally interested.
Give us a break - there is no Giopan ghost hunting AF. You already have enough problems.
Quoting Pihero (Reply 9): we have a flight preparation before departure, at which we are provided with all the weather information available
And what happens when weather changes dramatically some hours into a 12-hour flight?
Quoting Pihero (Reply 9): AF crews in particular are well aware of the particularities of tropical weather, first by going through a thorough course on the subject, secondly by experience accumulated over 85 years or so. (We opened the South Atlantic route for the Europeans with the Germans).
That is surely a great achievement. But sadly, truly sadly, AF is the first to have such a big loss in this route.

Quoting Giopan1975 (Reply 19): And what happens when weather changes dramatically some hours into a 12-hour flight?
You can get 6hr, 12hr, 24hr forecasts... forecasts are just... forecasts... it can change.
For some items you can get hourly updated forecasts (such as weather forecast at destinations)... For enroute weather, the 6,12,24 is the norm, some items you only get the 12hr, some only the 24...
If your expected tailwind disappears or the zero headwind becomes a jetstream against you, tough... make an extra stop if you have to.
Aviation enroute weather forecasting is I believe, amongst the very best out there... not sure about those hurricane path forecasts though...
