I know it's the usual speculation, but IIRC in most nose over accidents, the fin collapses, and traps the pilot in a very bad position, bent over in a position where breathing becomes very difficult, or even impossible
A question for those in the know. I'd be surprised if the original aircraft design didn't consider this. So far as I know this design included a sheet of armour plating to protect the pilot's head from 6 o'clock incoming. Is it possible that this plate was, in fact, dual purpose, the secondary purpose being pilot protection in a full nose over. Is it possible that the plates have, mistakenly, been removed as redundant?
