The plane did not crash in the bay. the only part that went into the bay was the vertical stabalizer. They recoverd 100% of that in one piece.
Contrary to what has been posted, an airplane cannot fly without the vertical stabalizer. It is 100% necessary to have some yaw stability. If the airplane turns sideways, the inside wing loses lift and it rolls to that side.
That is how an airplane goes into a spin. Uncontrolled spins are always fatal.
Actually, spins result from improper recovery from stalls.
