    Looks like it stalled due to lack of thrust. What could have killed both engines right after takeoff?

      It seems to climb OK for a little while then suddenly start sinking. There’s no sign of an obvious engine problem. Not sure whether we’d be able to see any sign of a bird strike from this far away.

        bird strike taking out both engines? nah.

        This has to be pilot error. Even at stall, it looks like pilot didn’t even try to level out.

          Why not? That’s the reason Sully had to land on the Hudson.

          They were like less than 200m from the ground. There was literally no space to recover from the stall. You need some altitude to pitch the nose down and recover from a stall.

      For multi engine planes it’s pretty rare, most likely a fuel system failure, or less likely pilot throttling error. My money would be on something with the fuel system.

      I was just thinking about this, perhaps when the aircraft rotated, water or other contaminants got drawn into the fuel system?

      Or shifting cargo damaged the fuel lines?

      It’s always hard to judge AoA unless you’re looking side-on with a horizon for reference, but excessive nose-up attitude caused by cargo incorrectly loaded or not secured properly so it shifted aft during rotation could have caused an aerodynamic stall.

        It’s a passenger plane. I don’t think 200 people slid to the back of the plane after rotation.

      Maybe, maybe not.

      What’s way weirder is that he’s got zero flaps and gear is still down, which is the exact opposite of what you want to do when climbing out. Maybe pilot error (control inversion)?

        Slats are 100% deployed, you can see that in the videos, indicating the plane was in Takeoff Config. Now, the flaps themselves are hard to make out in the grainy videos and they don’t extend much on takeoff. Edit: https://imgur.com/a/JzS3ro9

        Much more important is the lack of engine noise. We can also see the rat turbine was automatically deployed, indicating a complete loss of power only seconds after they rotated. Which is also why the landing gear did not retract.

        I don’t know what could’ve caused a dual engine failure, simultaneously, immediately after takeoff but that seems to be where everything is pointing to. Possibly problems with the fuel?
