Really? I'm looking at our Oceanic Driftdown Checklist, which have about 11 steps before making calls and touching the transponder.

I am discussing contingencies in the context of being on the tracks, but I don't know exactly what coverage these guys were working under. Even if I was in VHF and radar contact, I'd perform a number of tasks first, before talking to anyone. They might only take 20-30 seconds, but there is a window there, where I would be preoccupied with things other than ATC. With the very incomplete picture I have, it makes me wonder whether it's possible these guys started a few steps, got the aircraft started down, and passed out while within that window. Maybe the oxygen was not fully open, maybe they didn't put it on, maybe there was a fire. I have no idea, CNN definitely has no idea, and based on the unverified information available to the public, I'm pretty sure most of us have no idea. |

99% of the time there is time for at least one mayday mayday call out flying over the ocean that would be the first thing I would do. Very few malfunctions would take out all three radios, but going silent is the one of the things that can happen during a hijack or crew involvement.

The oxygen line theory would explain a lot. I don't understand, in light of the Egyptair fire that gutted the cockpit, why AD 2012-13-05 gives the operator 18 months to replace the hoses. It seems it would be an emergency AD note with a 'replace before further flight' restriction. If the oxygen line does turn out to be a factor the airline will get tagged for not changing the line, Boeing will get tagged for installing the defective line it in the first place, and the FAA will get tagged for the 18 month compliance window. If I were a pilot on the 777 I would make extremely sure the lines had been changed out. Before further flight

The last known position is about 370 nautical miles from the oil rig--well over the horizon; impossible it was the B777 being seen on fire.

Yes, the Sig crash. Paint, undisclosed, caught fire, airplane virtually burned down in the traffic pattern. GF |
Eyewitness reports placed this woman in the crew hotel the night prior to that fateful flight. Gee, it is fun to write news.
Or maybe she was looking for her husband. Right now the National Enquirer has far more credibility than the NYT or CNN. http://i237.photobucket.com/albums/f...psb3fee3ef.jpg |

Twin Wasp,
40 years of aviation here and have worked with the FAA on at least ten different AD notes as an employee of an engine manufacturers as well as an employee of an airframe manufacturer. What part of the 'business of aviation' don't I understand? |

Medically, most people would lose useful consciousness at cabin altitude 30k ft within 20-30 seconds. If plane was started down though via the FD, and reached 12,000 ft as per some reports within 20 minutes, everybody would wake back up with little more than a bad headache and maybe some brief confusion. Obviously smoke changes everything. |
