On my way home last night, I was listening to local all-news radio station.(CBS Radio) I only heard the last few lines of a report regarding the CI #611 crash last week. They said investigators are now trying to determine why the 747-200 performed a series of violent maneuvers about 8 to 10 minutes prior to the breaking up of the plane.
If anyone still has the ATC transcript, did the CI pilots report this to the ATC? Was it turbulence or something?

Here's an update, according to CCTV English news(Telstar 5 in North America), the CI 747-200 made at least ten sudden acceleration/deceleration TWO & HALF minutes prior to disappearing from the Chinese air traffic radar. The plane's direction also chaged left/right, up/down several times at the same time.
The same broadcast can be seen via Newsworld Int'l, a Canadian channel that re-broadcast news from foreign stations. (channel 364 on DirecTV)

If true, that pretty much eliminates the collision,fuel tank, missle, or bomb theories. It could be one of those one in many billion confluence of multiple events (clear air turblulence, unlikely structural failure) that may never be explained.

If it turns out to be technical problem, it had to have been huge. A 747 is designed to withstand 9Gs of stress. It would require a tremendous amount of force to break the plane into four parts. Same for turbulence. I wonder if the joints of the fuselage undergo maintenance during a D-check.

If thats true (and why should it be untrue?) the center fuel tank explosion theory is dead. A possible scenario could be that a clear wheather turbulence caused a already weak structure to break.
Or could it have been something like the Lauda Air desaster 11 years ago (reverse thrust misfunction)?
What about the reports of meteorites going down at that time? I read something like that here.

I think the only doubt is the completeness of radar data. They are still compiling information to ensure the radar returns were not erroneous. I don't doubt the veracity of the radio report.

Someone sent me all the radar data last week. Unfortunately I deleted it off my computer, but it did include several sudden speed drops on 100+ kts associated, if I remember correctly, with heading changes of 90 degrees to the left in a turn that took 11 secs, (Quite a steep turn when at altitude) and then a few minutes later, after recovering heading to track heading, another change of 90 degrees or so, also for 11secs to the right.
If this was associated with steep climbs and descents as well, I wonder if something happened to the rudder/evelator assemblies. Perhaps the rear pressure bulkhead blew out taking some of the control surfaces with it?

That's not aircraft-caused. There were external factors ie turbulance.

I don't think that the CI were in a known area of turbulence, unless there were thunderstorms that day which they decided to fly through. Does anyone have weather data for that route at the time the a/c went down?

I think China is doing a VERY bad job of covering up an OBVIOUS dogfight.
I remember one time I saw the Concorde doing all sorts of evasive manuevers avoiding fighter jets and missiles, adn eventually crashed in the snow.

Re: JAL incident.. i'm thinking the same thing....
It sounds like the plane is "fishtailing" in the air, which means the tail assembly was absent or rudder fell off.. but if you loose a rudder, you can *technically* still fly... it wouldn't cause you to blow up. Now if it was hit by another object, then that *should* show up on radar...
Could it be possible there was an extreme depressurization, which would knock everyone out in about 5 seconds at that altitude..... ??

A high altitude upset can easily cause the aircraft to perform violent manoeuvres to the point of structural failure. In fact in 1985 China Airlines had it happen to one of their 747SP's although it didn't come apart. http://www.ntsb.gov/ntsb/brief.asp?ev_id=20001214X35672&key=1
One more thing: 'A 747 is designed to withstand 9Gs of stress'

I doubt the mainland has anything to do with the crash.
Losing a tail would not cause the aircraft to break up, but that's what the AA A300 started to do last year after it lost it's tail didn't it? It it was at 30,000ft, it might have fallen to bits as well.

The data above get me feel;
1. the location data east and north from no. 6 does not seem to reflect the ACTUAL locations. Plotting them the aircraft is flying the zig zag way even the fighter could not do.(only a flying saucer could)
2. if I can ignore the location data, the aircraft seem to enter to a horizontal spin from the left to the right.
3. data of the speed and the altitude look like to have mutual relationship of a certain significance; when the altitude lost, the speed gained. when the altitude gained, the speed lost.

T-prop and Admiral Ackbar,
The 747 is designed to survive 9gs of stress intact- not meant to be operated regularly under 9gs. I have heard/read that in several places: Discovery channel, Boeing Everett tour, and other places. I don't catalog the stuff but I don't make it up either.

"Is there any benefits that the People's Republic of China can get by doing so to the Republic of China ? I am not clever enough to figure it out. "
Actually, there are many reason why they would shoot down their own plane.
Feeling that they need to eliminate one speicfic passenger on board or somethign that we may never understand.
But why could it only have been China? Who said it's not a terrorist attack form some other country?
