If you haven’t seen it yet, take a look at this video of the Martin Aircraft Company’s recent mile-high test of its personal jetpack and safety parachute system. The flight topped out at 5,000 feet, but could have gone higher. While a dummy was on board for this test, the New Zealand-based company is marketing their $100,000 jetpack as personal transportation, with special appeal to military and rescue workers. The design goal is to fly for up to 30 minutes at top speeds of 63 miles per hour. And if the gas-powered, two-stroke piston engine conks out, there’s always the parachute.
