Sorta kinda think that
"....longer period..." is a bit relative.
From the available videos and the two people I've met who survived ejections (one with lumbar fractures and the other with a broken arm) it seems to be a pretty violent event
Suspect it beats impacting
terra firma with the aircraft though...
John Stapp, Jim Hall, Joe Kittinger, Yeager and all the other early guys at Muroc, Holloman and all those friendly desert places are the real heroes. Not forgetting Doddy Hay and the rest of them outside the US either.
