Documentarian Sebastien Montaz-Rosset filmed some insane, insanely brave people attempting to tightrope-walk across hot air balloons. And here is the video! Don’t watch it if you’re scared of heights or of falling off hot-air balloons.

I assume everyone had parachutes, although we don’t actually see them get pulled, which is, uh, discomfiting. Someone does have a parasol, though, and you can probably just Mary Poppins your way down with one of those. So we’re good.
