If the terminal velocity of a human is c120mph, how did Alan Eustace fall at a reported 822mph?

I was just scrolling through another sub and the Felix Baumgartner jump came up, along with someone mentioning that the record was broken by Alan Eustace in 2014.

In the Wiki for this, it mentions he was falling at 822mph, however I thought a human’s terminal velocity was 120mph (more if say, a skydiver was diving head first)… So how does this work? Is it as a result of the reduced air resistance and force of gravity increased therefore increasing the terminal velocity?

Sorry, by no means a physicist!

This is pretty straight forward. He fell quite a while in vacuum or near vacuum. Since it’s air resistance that dictates terminal velocity, he was able to fall much faster than this for a time before entering the atmosphere
