Stalling or spinning into the ground is invariably fatal although I am not saying this is what happened in this case.
While that is the case in most stall spin accidents it does vary from aircraft to aircraft. There is a 4 seater Canard (Velocity)which on its test flight was stalled. The test pilot could not get the aircraft out of a flat spin and to save the only test airframe opened the canopy and attempted to break the flat spin by putting his body weight towards the nose.
This failed and the aircraft spun to the ground landing on a beach. The test pilot climbed out and the same airframe was repaired and used again.
As stated in a spin the vertical speed is relatively low compared to a dive. One witness described the engine sound like a high speed drill and the accident would look like a high speed dive crash.
