There was one flap setting (5 If memory suits me) where the Boeing test pilots did the heavy aft cg inverted thing and ended up losing nearly 20,000 ft of altitude before getting it back at around 2500 ft.
Just had a friend go up in a learjet test flight where they entered stall and it would not push over and they fell for like 20 seconds with it kicking and bucking all over the place. Full redline power is the only thing that saved them.
i think thats enough to frighten the !!!! out of anybody!
how far do you reckon they will go with stall testing on the a380?surely they will only be incipient stalls.
