Falcon 1 Demo 2 launch

The 2nd-stage rocket bell glowing red or above is normal, but that tap by the first stage definitely knocked the rocket off course. The 2nd stage rocket tried to compensate and it almost did but probably overcompensated a bit. This along with the strike is probably what caused the oscillations the eventually threw the rocket into a death spiral.

That was SpaceX's conclusion as well.

@NittanyTiger1 I don't think the tap had much to do with the rotation. The tap may have started some slosh in the tanks but the engine is most probably chasing the propellant swirl in the tanks. The fix is baffles in the tank and a more robust control system, which would prevent this type of engine motion.

Great video ! Thanks robotguy for uploading and for the precision you wrote with it. I'm pleased to see Falcon 1 is on track for paving the way to falcon 9... to the ISS !
