Smudge hydraulic control
Smudje. Only done in Sim. Loss of all hydraulics to flying controls needed the combined and co-ordinated input and strength of both pilots to control the aircraft. I would look for completely calm or no w-wind runway and spend all day setting up about a 20 mile final approach and cross all fingers and toes. Asymmetric power inputs were too slow to cause a reaction and it was too easy to lose it!!!!!
