When is a daredevil stunt jump actually a "jump" and when does it become a form of ill-advised rocket flight? While we enjoy the dramatic and circus-esque musical soundtrack in the video, let's also appreciate some interesting physics issues relevant to Kenny Powers' unsuccessful jump. I'm not sure how carefully they thought this one through, but I suspect at least they must have recognized that their "souped-up" Lincoln Continental had to be under rocket power not only during the approach and up the ramp but during the jump (flight) as well.
We advised "thrill seekers looking for something new to
try" to check out Viennese daredevil Joseph Krupka's wing-enhanced skiing technique. Krupka skied partway down a glacier, then tilted his aluminum wings and "for hundreds of feet soared over the snowy tracks, landing near the foot
of the slope." The practice of enhancing a traditional sport
by adding wings has endured; witness how intrepid modern-
day "skyfliers" have expanded skydiving.
