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

Yea really my buddy 777 driver and myself were just talking about this we both agree first thing mayday. You really can't say mayday while the other guy is getting the drift down checklist.

I don't know what you mean by the second sentence, since it contradicts the first, but I'm going to assume to you're saying "mayday first" is the way to go. Maybe that's how you guys fly, and perhaps my procedures are incorrect. Our philosophy seems designed to prioritize aviating, then navigating, and communicating last. Seems pretty logical to me in cases where you have seconds of TUC, or a few knots to E/O speed. Not being sarcastic when I say this, but it seems pretty basic to me.

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.

Wasn't there a 141 that crashed shortly after takeoff out of Sigonella, the crew had been overcome by chemical fumes, not sure if any calls were made.

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.

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.

You don't understand the business of aviation.

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?

Yep - almost all cabin pressure recall checklist step 1 oxygen masks and regulators ON.... of course depends on the oxygen and mask delivery system working.

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.
