The Martin “Jetpack” actually uses two ducted fans powered by a gasoline engine.
On the plus side, a 30 minute flight time with a max speed of 97 kph (60 mph). That gives it a one way range of about 30 miles (48 kilometers). That is a lot better than the 30 second average flight time of an actual jet pack.
Well, if you’ve got all that air out there, you might as well generate thrust by moving it.
Wasn’t there somebody coming out with a true Jetpack, that used small Jet turbines intended for R/C planes?
And oh, I always thought that those Hydrogen peroxide packs were technically rocket engines, so it would be “rocket packs” and “Rocketeers”. 🙂
