Ben, don’t forget that this is the same plane that lost a wingtip in an on the ground collision with the tail of a Chinese airliner. What if the wing failed, and broke up?”
Certainly can not be discounted, but while it would certainly haved pulled a lot of G's to lose a wing, it shouldn't have wiped out electronics and communications immediately. Nothing from the Pilots assuming, they were not out of the cockpit, or asleep. Hell what do I know, they probably were pissing their pants as would I would be when the SHTF.
I would hope both pilots were still awake and alert just 41 minutes after takeoff. That’s when the plane disappeared, after 41 minutes of flight.
“Nothing from the Pilots”
If the wing were lost, the plane would probably have flipped over so fast, that there may not have been time to do anything, assuming the flight crew was still conscious. I have no clue.
