Yeah and the other pilot flipped the switches back on and one of the engines started spooling up but it was too late.

Murder-suicide looks like the likely conclusion, given that flipping the cutoff switches requires a very deliberate action. That said, it's not entirely impossible that due to stress or fatigue the pilot had some kind of mental lapse and post-flight muscle memory (of shutting off the engines) kicked in when the aircraft lifted off.

Possible, and if so it is too early to conclude it was murder-suicide.

  • The report shows 0 flight hours during the prior 24 hours for both pilots, and 7 hours and 6 hours each for the previous 7 days. It seems they were both fresh pilots for this flight.

    • 0.1% of airline pilots fly intoxicated, and probably many more fly hangover which is an undetectable condition.

      There is speculation that in the Air France flight 447 that crashed into the ocean en route to Paris, one or the pilots only had 1h of rest because of partying the night before. Of course it’s all speculative, and however unlikely it is, eventually it’s bound to happen that we get pilots with poor mental clarity in charge of large Boeings with hundreds of lives on board. Unfortunately it only takes one lapse of judgement to compromise the flight profile of a large airliner, even if corrected after a few seconds.

But why cutoff the fuel instead of flying into terrain? It's such a passive action

  • For whatever reason, the Egypt Air 990 pilot initiated his murder-suicide by pulling the thrust to idle and then flipping the fuel cutoff switches.

  • I imagine it would be more difficult to fly into terrain without a cooperative co pilot than cutting the fuel just after take off.
