Maybe the pilot in the cockpit was already dead and the door banging pilot was putting on a show for the “black box”/passengers.
Can the auto-pilot be put on a timer?
(I know that’s a stretch)
You still end up in the same place...an amazing set of coincidences for a crash that was clearly not a result of terrorism.
What if BOTH pilots were inside the cockpit all along?..
Okay "WHAT IF BOTH PILOTS WERE INSIDE THE COCKPIT, ALL ALONG?!!"
