There is a classic piece of film of a a very brave and humble American serviceman stepping out of a balloon gondola at the edge of space and dissapearing Earthwords in an eyeblink.This was during early days of high atmospheric flight and space travel.The guy was "Just doing his job"and was a contrast to the self publicising danger freaks who do these things for to see themselves on TV.I seem to recall he was just some regular bloke off the base who recieved a few bucks bonus for these trials.At interview he says something like "I was given the go ahead so I opened the gate and stepped out"(paraphrased)..Absolutely mad.
Perhaps somebody with a guiness book of records can elaborate.
