Jamaican sprint legend Usain Bolt was back on the starting line Thursday -- but found it a challenge to stay on his feet in zero gravity conditions aboard an aeroplane.

The 32-year-old briefly broke off from his pursuit of a professional football career with Australia-s Central Coast Mariners to travel to France for the event. Dressed in a spacesuit, Bolt was aboard a zero gravity Airbus as part of an event sponsored by a champagne brand.
