I didn't even know that it was possible for a non-professional stunt-person to do wing-walking on old pre-WWII biplanes. But I suppose that if you're a risk-taking billionaire, you can find a way. Elon Musk and his wife Talulah Riley, along with the rest of the Musk Clan (brother Kimbal, mother Maye, sister Tosca), somehow found UK-based Breitling Wingwalkers and went for a nice stroll together... on the top wing of a plane going 130 MPH.
A few photos from the family outing were shared on Instagram, so for your viewing pleasure, here's something you don't see everyday.
Here is the video showing Musk doing a bit of wing-walking...
Here's some promo videos by Breitling Wingwalkers showing some of the daredevil things they do:
