On a side note, while I was researching ejection seat labels I came across this interesting photo:

No caption given, but based on the seat being hoisted up the rails and the eye line of the gent in back, probably has something to do with "sizing" pilots for the T-33 ejection system. My own father was 6' 4" when he was twenty years old, pretty tall for a fighter pilot. He once told me when I was a kid that the F-86 would not have posed a problem for him but if he ever had to get out of a T-33 he would have had to pull a WW2 - jettison the canopy, undo his straps and jump out or roll inverted and fall out. Using the seat could have robbed him of his legs from the knees down, or his kneecaps at the very least!
These days there's an elaborate template you sit in during aircrew selection for this very reason.
