Troy Hartman is a man that indulges in senseless acts, and his website proves it. No seriously, his website has a button that says “senseless acts”. So it’s no surprise to see him strap on a home made jetpack and hit speeds up to 47mph on a pair of down hill skis. And that’s at 50% throttle, so presumably speeds upwards of 80 mph are feasible.
Unfortunately, that’s all we know right now, but Troy says he is still tweaking the system.
In case you’re wondering, he used a GoPro HD camcorder.
