It’s probably safe to say Elon Musk isn’t afraid of heights, given that he runs a space exploration startup. But now we have definitive proof. The Tesla and SpaceX CEO posted a picture of himself on Instagram standing atop an airplane as it flies through the sky. The daredevil stunt is known as wingwalking. “What could go wrong?” Musk asked in the photo caption.
Musk’s wife, Talulah Riley, also got in on the fun and posted a video of herself wingwalking. The couple was flying with the Breitling wingwalking team in Hampshire, England, according to a comment by Riley on Instagram.
