As the video explains, switches are virtually impossible to operate by accident. Were switched to OFF just after the plane rotated and lifted off, because the computer was in “Air” mode, meaning the wheels were off the ground (this is controlled by sensors in the landing gear).
Another video explained that, after the switches were moved to OFF, one pilot asked the other “Why did you do that?”, to which he replied “I didn’t”.
Switches were moved back to ON and engines began to relight, but it was too late.
“one pilot asked the other ‘Why did you do that?’, to which he replied ‘I didn’t’.”
Was there another person in the cockpit?
Could the switches have been placed in an intermediate position that could change to ‘off’?
Is there any other switching system that works similarly in the type of airplane?
Was either pilot certified on another type of plane that would require a similar switch to ‘off’ movement during a takeoff?
Did the pilots get enough rest before the flight?
