When base jumping isn’t enough… there’s always the wingsuit:
What strikes me about the wingsuit, once I pry my heart out of my stomach, is its simplicity. With humans trying for millenia to fly like the birds, with the airplane having been with us for more than a century, it seems odd that the wingsuit is so simple, so elemental, and yet took so long to develop. “You need webs, like a bat!” Why wasn’t this invented a thousand years ago? Almost seems like it could have been made with deerskin and twine.
OK, I take it back. Wikipedia:
According to wingsuit lore, between 1930 and 1961, 72 of the 75 original birdmen died trying their wingsuits. Some of these so-called ‘birdmen’, most notably Clem Sohn and Leo Valentin, claimed to have glided for miles and inspired dozens of imitators.
