A lot of the modern work on crashworthiness goes back to Dr John Stapp's experiments in the early post-war years. He subjected himself to decellerations of 45 g in a rocket sled slowing from over 500mph and wind blasts of over 500 mph with only minor injury.
A curious effect of his research was that the observation that the military crews were involved in mode survivable accidents travelling to and from the base in their cars than they were in operational flying.
He then went on to pioneer much of the work in automotive crashworthiness.
I suspect crashworthiness may enter into peoples decision making when buying aircraft at some time in the future, in the same way that it has for cars. At present, there is very little information in the public domain to use as a basis for assessment, and who's going to pay for an aircraft equivalent of EuroNCAP?
