Wrong. Neither of the two would have done any damage. They broke the glider by doing both things at the same time. No. With the Spanish tragedy the pilots didn't open the airbrakes but the P1 broke the wings by pulling back too hard. Presumably it wasn't necessarily Vne that broke the wings but excessive load (pulling back too hard in a panic) once past maximum maneuvouring speed? Given the P1's self-confessed lack of currency in spin-training (paraphrased from memory; "did it once twenty years ago and swore never again") is it fair to say that without the panic from an unpractised situation the spin and resulting dive recovery might not have broken the wings? Limiting your spin recovery to just pulling back hard is going to have unfortunate consequences which ever way it turns out. That said, it was a terrible thing to happen and my heart really does go out to the pilot and his family. The Minden tragedy involved opened airbrakes which in turn contributed to breaking the wing. Still from pulling back too hard, but in quite different circumstances where "too hard" might not have been so apparent because of the reduction in wing area and thus perceived wing-loading. But had the airbrakes not been out the wing might have sustained the load. Though Vne may then have been passed. So it would seem the answer is to not open the airbrakes but respect the yellow band on your ASI when loading the aircraft with g. Even if this means passing through Vne? Or, if you do open the airbrakes in a last ditch attempt to avoid breaching Vne be even more respectful with the loading when pulling out of the dive.
