luciopercaon What flying was like fifty years ago

You can absolutely try switching to reverse at 200km/h in a manual transmission. car at cost of your tranmission and potentially your bones in you hand. If you do it while rolling forward it will make funny sounds.

Apart from that the pilot flying the aircraft was totally confused and pulled the nose up while having stall warning and actually stalling. That is quite some remarkable screw up not understanding to stall and thinking having your nose at an high attack angle while having 100% engine thrust will solve anything in this situation. Sure with non-independent joysticks the other might have called the non nonsensical maneuvers earlier and prevented it. But the lack of awareness in instrument flight of that pilot is quite remarkable.
