It may or may not surprise you to hear that jet packs (of a sort) are old news. Bell Aerosystems had a personal rocket belt back in the 1960s, and a few different companies are currently offering the same hydrogen peroxide powered sort of thing, including Tecaeromex, from whom you can buy a working version for $250,000. The downside of rocket belts is that they only get a maximum of 30 seconds flight time, and the fuel is expensive and dangerous. Bell Aerospace started working on an actual jet pack in the late 60s, which had a hypothetical flying time of 25 minutes and a top speed of about 80 mph, but dropped the project due to it’s complexity.
