Tired of the limited legroom, bad food, and worse movies you have to put up with during a flight? Well, it's time to bust out your company credit card and get yourself a Martin Jetpack, which has just become the first commercially available jetpack. Driven by a pair of washing machine-sized fans strapped to your back, this personal transporter will give you a pretty cool 30 minutes of flight time and comes with a bunch of redundancy systems to ensure any mistakes don't turn fatal. The rotors are built out of a carbon / Kevlar composite and are powered by a two-liter V4 two-stroke engine capable of delivering 200hp (or 150kW). Good old gasoline is the fuel of choice here and private individuals are expected to be offered the chance to fulfill every geek and geekette's dream later this year. Just make sure you have $86,000 lying around to fund it.
