Well not really that giant leap, since Joseph Kittinger basically did the same jump 50 years ago [1].

He actually was in freefall longer (4min and 36 seconds), which hence is still the world record. Since Felix "only" fell for 4min and 22 seconds.

Also, as Neil deGrasse Tyson funnily put it: «I'm told somebody's jumping out of a perfectly good balloon from 23-miles up. The theory of gravity no longer needs to be tested in this way» [2]

But still, cool video and congrats to Felix and the Rebull Stratos team.
