Rafale flying slowly
Discussion

High angle of attack and all lift devices deployed, combined with a lot of thrust from those engines overcoming the tendency to drop like a stone.
I doubt it would be possible without fly by wire as the aircraft is right on the edge of stalling.
How much margin for error is there since this is a public display?I doubt it would be possible without fly by wire as the aircraft is right on the edge of stalling.
If it does stall what happens?

Nope, just balencing on thrust. Mig 29s are old buses these days, generation behind the rafale.
The russians liked to brag that their jets were the only ones "capable" of performing the maneuver, but I suspect the truth was more authorisation.
To me, thrust vectoring is a gimmick. If you need to use it in a combat situation, you’ve fked up, big time. The russians liked to brag that their jets were the only ones "capable" of performing the maneuver, but I suspect the truth was more authorisation.

I still don't really get it, rocket engines engines are so powerful in comparison to the weight of the vehicle that they're attached to that the rocket can fly without requiring the lift generated by wings, don't planes require a combination of thrust and lift to remain airborne but this clip seems to contradict that?
It's a combination of the two at that angle.Lower airspeed, less lift. Higher angle of attack, more lift. At a first approximation lift has to be greater than the weight of the aircraft. But at that angle the engine thrust, while being less than the weight of the aircraft, is effectively making it lighter. So the angle of attack can be lower yet providing enough lift to stay up.
When Eric Brown was asked to land a Mosquito on a carrier he calculated that the landing speed would have to be less than the stalling speed. Or to be more precise, less than the speed at which the necessary angle of attack would be on the edge of a stall. But he was able to land at a lower angle of attack using the engine power to reduce the rate of descent.
