We don't know what exactly happened to the company Skywalker Jets and its promise last year to make jet packs commercially available, but here's a heads up to all of you who really want one and have the money to fund their desires: two companies are currently selling jet packs and promising to keep you afloat for at least 30 seconds.

Mexico-based Tecnologia Aeroespacial Mexicana (TAM) is currently offering TAM Rocket Belts for US$ 250,000 each. This package includes the gadget itself plus flight and maintenance training modules. It's being fueled by hydrogen peroxide and on a full tank, the jet pack weighs 124 to 139 pounds - all depending on the size of the pilot. TAM promises 30 seconds of flight.
