So some footage I used it's from an Nasa's experiment called Project Excelsior 1959/1960 That guy Joseph Kittinger passed through atmosphere about 31 Km altitude by Helium Baloon (so you right !). If I remember right, after him others try to do something similar, but all of them died. Anyway I liked to use those frames, in that way, just for editing reasons But of course I aggree with your remark
