He's the fastest man on Earth ... but how would Usain Bolt do in space!??
You're about to find out ...
The Olympic legend boarded a special Airbus Zero-G plane, which simulates what it's like to be in zero gravity ... and challenged 2 of his fellow passengers to a foot race.
The challengers? French astronaut Jean-Francois Clervoy (in the blue flight suit) and CEO of Novespace and French Interior designer Octave de Gaulle (in the black).
The guys definitely gave Bolt a run for his money in the first leg of the race, but Usain turned up the heat and crushed 'em when it counted.
