I was reading this article on the BBC today about a guy who is going to make a parachute jump from 40 km high (131,200 feet)
Here is some persepctive on how high that is:
I thought this quote from the article was amazing:
In so doing, he will fall further and faster than any jumper before him, reaching supersonic speeds between 1,200 and 1,600 kilometres per hour (between 745 and 1,000 mph).
Here is the article.

It is pretty cool read how fucking crazy this guy is.
