How Long Can a Man Survive in a Deadly Space Vacuum?

Here at WonderHowTo, we certainly have an affinity for outer space-related topics, so I couldn't pass up this horrifying video of a man who just barely survived a simulated space vacuum.

Back in '65, Jim LeBlanc stood in as a test subject for a dangerous NASA test, in order to determine if space suits could handle a zero-pressure vacuum (as such is the state of the moon).

But the tube pressurizing his suit became disconnected, and the effects were instantaneously life-threatening.
