The speculation on this accident has been focused on blunt force
trauma to the head or face. Another possibility is a severe cut from
the fins to the head or neck. I've witnessed balsa wood fins leaving
deep groves in wheel fenders from near miss lawn dart model rockets.
A thin plywood or fiber glass fin would be equivalent to a knife
blade. Something to think about.
