Actually, spins result from improper recovery from stalls.
The technical cause of a spin is when one wing stalls and the other does not. A snap roll is a horizontal spin, and the airplane is not near its "stall speed".
A snap roll is executed by abuptly pulling up and swinging the tail to one side while also using full aeleron. It is caused by making one wing go faster than the other through a yaw motion.
An airplane without a verticle stabalizer would yaw and start a spin. The spin is caused by the yaw motion and not from "improper recovery from a stall".
Improper recovery from a stall is one way to go into a spin, but is not the only way. Even then, the spin starts because of a yaw motion. If the rudder keeps the tail behind you, there is no yaw motion and so no spin.
As to the DC10 with loss of hydraulics, it still had a measure of yaw stability from the verticle stabalizer. The pilots used differential power in the engines to replace the control normally given by the rudder.
The loss of hydraulics was while in stabalized cruise and not at takeoff. Everything is more crititcal while taking off or landing.
As to the Israeli jet that landed without a wing, -- the body of the aircraft is shaped like a wing and gives enough lift that together with the remaining stub of a wing, gave enough wing for flight at high speed. He landed very fast.
