So, I was all set to send this article to a tri-athlete friend of mine based on the title alone, "Jet-Powered Bicycle Makes 50 MPH Feel Waaaaay Too Fast". I titled the email "I think you'll want one of these" but then I read the article and saw the second photo.
Maddox has been into skydiving for 20 year and used to compete in tracking contests, where free-falling skydivers move horizontally across the sky at speeds approaching 120 mph. His buddy was always just a little bit faster, so Maddox thought "it'd be fun to strap a jet engine to my chest and make myself into a human missile."
Holy cow, I want one of those
I used to skydive a lot until discretion also got the better of me but I can definitely understand how "it'd be fun to strap a jet engine to my chest and make myself into a human missile"
