Martin Jetpack

Unlike earlier devices called "jetpacks", the Martin Jetpack is the first to be considered a practical device. It has been under development for over 27 years and uses gasoline (premium) engine with two ducted fans to provide lift. Theoretically it can reach a speed of 60 miles per hour, an altitude of 8,000 feet, and fly for about 30 minutes on a full fuel tank. The consumer price is expected to be US$100,000. Martin Aircraft planned to deliver the first jetpacks to ten customers in early 2010
