Well, maybe they had a scrape. But apparently their engines were able to spool up and provide TOGA thrust. So why schould they both, quite simultaneously, suddenly cut out? Why no APU start? (RAT...

Do you positively know there are no bio-fuels added to jet fuel? All over the world?? Would be relieved to hear that. But, please, only if you truly *know* that this is the case.

How comforting. :(

But it really comes down to what happens with pax (and flight crew!) upon approach/landing. If the past travel record is available for every single person on board a flight, why...

Tracking of passenger's previous flights re. 2019-nCoV

In light of the coronavirus crisis, what technical means exist to track where a person disembarking had traveled previously?

Not just immediately preceding (connecting) flights, but flights taken...

Found this simulator video of a 737 trim runaway, what is the alarm at 2:57? And are the switches to turn off the autotrim still there in the newer 737s, and would they disable the MCAS?

Apart from the discussion if a ND trim automatism on a detected impeding stall (false or not) is a good choice, I think that any autonomous, severe intervention into the flight controls should always...

Hm, I think that is only partially true. Rigid procedures & training aim to make pilot behaviour both predictable and, consequently, identical.

In the case of AF447, we seem to see just that - but...

If I remember correctly, in the Airbus the trim wheel does not make the 'clack-clack-clack' sound that other aircraft do. Another example of technology that seems to be designed to withhold...

Exactly my thoughts. And it neither starts nor ends at the computer level: AF447 was not the first AC brought down by a pitot failure. The mistake I see there is what I call 'false redundancy'. While...
