The motorised ski arms race has hotted up recently with Troy Hartman, a self-proclaimed ‘gravity athlete’, bringing a jetpack to this particular knife fight. He claims that he can hit 47mph at only 50% throttle and in this video demonstrates his new invention on a black diamond run – as if no one would be impressed with him flying around a nursery slope.
The set-up currently costs around $40,000 so don’t expect to see slopes being littered with critically injured rocket-skiers just yet.
