>>16952065so it seems.
he even turned the autopilot to 100 feet during the outward flight when the other pilot left the cockpit, just to test if it works. then he adjusted it into the initial state before he returned.
during the return flight he did it again when the other guy left and this time he left it like that until the end, at the same time he increased the speed to 650 kmh. it must have been horrible. the control center could hear the pilot and the passengers desperately banging against the door and trying to break through.
imagine you're a passenger and wake up from a nap and see pic related when you look outside the window.
