Condolences to the family and friends........ I guess we'll never know but I have the questions of timshatz. No substitute for altitude, especially with the glide factor of a P-40 being similar to that of a piece of granite. I believe if I was fortunate enough to own a Warbird that valuable I'd want to collect on the insurance I'd have on it, thus a parachute in the form of the original "fanny pack" type would be in order... I believe the seat was originally designed for the additional inherent padding provided by the chute. Hell, he may have had a heart attack or other physical problems that a parachute wouldn't have helped anyway..... When your numbers up, it's over for this side anyway...........10-4.
