Quoting holzmann (Reply 1): 5. Entire crew and passengers die within 30 seconds due to asphyxiation. |
Quoting holzmann (Reply 1): Try holding your breath for 30 seconds, see if you die. |
Quoting holzmann (Reply 1): I might put this hypothesis forward: 1. Front windscreen fails, perhaps even breaks. 2. Damaged glass incapacitates one or both pilots. 3. At least one pilot is able to reach the altitude gauge of the auto pilot and adjusts for something quick below FL10. Decent engages. 4. Said pilot dies of asphyxiation before he can push the button to drop O2 masks. Or perhaps can't see as he is blind due to broken glass / conditions in cockpit. 5. Entire crew and passengers die within 30 seconds due to asphyxiation. Aside from pilots, they die peacefully. 6. Everyone is thankfully dead when they encounter proximity warning. |
Quoting travelavnut (Reply 3): I was wondering if there is any news? |
Quoting holzmann (Reply 5): I've never held my breath at FL380. With perhaps a broken windscreen in my face, glass everywhere (if it indeed shatters?), and the feeling of 400 Kt airspeed in my face. |
Quoting holzmann (Reply 8): |
Quoting holzmann (Reply 15): But doesn't blackout occur in 10-15 seconds at that altitude? 30 seconds is irrelevant really. Just saying, what if the pilot's first reaction was to adjust to FL10 and NOT to don his O2 mask? There is only really time for one of two options in that case and assuming the other pilot is incapacitated, perhaps the wrong choice was made. Sorry for all the "what if" questions. I agree we should put additional speculation aside and wait for official announcements. |

Quoting LTC8K6 (Reply 6): 1. Front windscreen fails, perhaps even breaks. Wouldn't the glass blow outwards? |
Quote: If I understand correctly... Just push on the stick, the plane pitches down, then leave the stick in neutral with autopilot off. |
Quoting scbriml (Reply 9): Plenty of unfounded rumours, rampant speculation and the usual sprinkling of conspiracy theories, however (high-quality posts from the usual contributors notwithstanding). |
Quoting breiz (Reply 23): There are actually numerous instances of cracked windshield around the world every year. None of them has ever been catastrophic. The usual routine in such an occurance is to divert. There is the infamous incident of a Captain being partly sucked out from the cockpit because a wrongly fitted winshield glass failed. The Captain was held in position, half outside, by his colleague who managed to land the ac while keeping a good grip on the pilot's legs.

Quoting 777Jet (Reply 21): I am pretty sure that trying to hold your breath for 30 seconds or however long in the comfort of your living room at sea level would not be the same as trying to hold your breath under the above mentioned conditions... |
Quoting holzmann (Reply 1): 4. Said pilot dies of asphyxiation before he can push the button to drop O2 masks. Or perhaps can't see as he is blind due to broken glass / conditions in cockpit. |
Quoting holzmann (Reply 8): Crew O2...no. But PAX O2? I would assume the cockpit controls that. If pilots are incapacitated, pax get no O2, right? |
Quoting Rivet42 (Reply 18): Could a windshield failure (for whatever reason) account for the spike in vertical acceleration recorded in the ACARS(?) data during the gradual left turn immediately before the descent began...? The data suggests a very sharp jolt, following which the aircraft levelled out of the turn and immediately began it's controlled descent (I use the word controlled very carefully, because all the indications are that it was exactly that - it appears to have been commanded, and was maintained with little or no deviation). |
Quoting TheSonntag (Reply 33): The plane was untertaken a smaller check the day before the accident. In this, it has for example been disclosed, that there might have been a smaller problem with a door in the nose of the place. The door opens to a compartment, where the computers of the plane are placed and need cooling during the flight. When the airplane is on the ground, this door is opend. The danish sources clame, that if that door fell open during the flight, it could mean that cabin pressure has disappeared". Well, its speculation, of course, but Ingeniören is usually not a bad source. |
Quote: "Die Presse" was noted from well-informed circles of aviation experts that you have the cockpit voice recorder already largely evaluated - this is a pure digital sound file , the evaluation would last about half an hour . Thus , the testimony of a person who wishes to remain anonymous , had heard a sudden crash in the cockpit, as if something bests . " It was quick ," it says , and : The pilots had just can switch the autopilot on Notlandeanflug , then was nothing more to be heard within a few seconds . |

Here is the account: http://en.wikipedia.org/wiki/British_Airways_Flight_5390 The famous British Airways Flight 5390 incident you referred to occurred at 17,300 feet, not at the much higher altitude where this incident began... |

Quoting travelavnut (Reply 3): I have been offline since just after this disaster happened and haven't had a chance to read the previous 5 threads. As the media is still blaring about a computer problem (the AoA sensor freeze problem which IIRC was already fixed on this aircraft) I was wondering if there is any news? |
Quoting bgm (Reply 11): You're missing the point he was trying to make, and that is the body can survive without oxygen for 30 seconds. |
Quoting Rara (Reply 29): His assertion was that all passengers and crew were dead within 30 seconds from asphyxation. Living room or not, that's just medically non-sensical. |
Quoting BubbleFrog (Reply 35): I thought it was said earlier the nose-wheel is in an unpressurised area of the a/c? Or am I getting things wrong? |
Quoting b78710 (Reply 38): I initially assumed they were talking about the access door to the avionic bay, Having re-read it, it sounds as if they may be talking about the equipment cooling overboard valve, if this fails open in flight, there is no way it would cause a rapid decompression, its very small and i would imagine easily controlled by closing the outflow valves. |
Quoting holzmann (Reply 41): "Es ging schnell", heißt es, und: Die Piloten hätten gerade noch den Autopilot auf Notlandeanflug umstellen können, danach sei binnen weniger Sekunden nichts mehr zu hören gewesen. It was fast. Meaning, the pilots had enough time to select the emergency landing feature and then there was nothing more to be heard. |

Quoting bueb0g (Reply 43): Yep, it's unpressurised. |

Quoting TheSonntag (Reply 33): , that there might have been a smaller problem with a door in the nose of the place. |
Quoting TheSonntag (Reply 47): If so - and please excuse this speculation, I am just asking - wouldn't the SOP be "mask first, autopilot later"? |
