Tesla/SpaceX CEO Elon Musk Walked Across A Flying Biplane

Elon Musk, the man behind Tesla Motors and SpaceX, and his wife, actress Talulah Riley, both tapped into their inner adrenaline junkie and walked across the wings of a biplane as it was in the air.

“Went for a nice wing walk,” said Musk on his Instagram. “What could possibly go wrong?”

As it turns out, the 130 mph wingwalk went off without a hitch. Musk was in the company of the Breitling Wingwalking team in Hampshire, England. Their website advertises wingwalking for approximately $620 per session.

Check out this video posted by Riley on her Instagram demonstrating the wingwalk in action.

Here I am, wing walking! #wingwalking
