Can you get any lift if the hydrolics of 1 wing are done for? That is more than an engine failure, that thing ejected itself from the plane. That had to of damaged that wing severely. It looks like the runway is elevated and thats all the height the plane had before hitting trees/buildings with its tail and rolling in the air to its left.
That's what happened to AA 191. At first, they thought a bolt broke and the engine separated from the aircraft. Then, they realized, no, that the entire pylon gave way (the engine went up and over the wing) and that was due to improper maintenance. However, just losing the engine didn't doom the plane. Why couldn't the pilots fly out of it?
They realized the physical loss of the engine caused hydraulic lines to sever, which included the stick shaker/stall warning system. The pilots were trained to gain altitude in an emergency situation in a takeout and, without the stick shaker, didn't know the plane was stalling. Instead of lift, they needed to apply power. They ran simulations of the takeoff conditions, first letting the stall warning go and later turning it off. With the stall warnings on, everyone landed the plane safely; with it off, they all crashed.
However, even with all that, the flaps/slats were stuck due to hydraulic fluid loss and its unlikely the plane was recoverable. I don't remember if the simulations were done before or after they discovered the status of the slats.
