you could do it in a glider with a pressure suit over the Andes, well 50,699ft so 60,000ft + in a lightning, EASY.
If your pressure suit fails in any flight in or above that Level then the result would be the same or similar regardless to the vehicle your in, also look at the fact that the human race always seems to be pushing the envelope, not all but their not the ones we tend to remember.
Now that doesn't make it right to push past limits, but the temptation to do so is too strong for some who still have the frontier pushing way of thinking.
Sorry to say I play safe so you will never know of me past this site.
