A man named Glenn Martin in New Zealand has created a fully functioning, relatively safe jetpack à la many of our superhero fantasies. Except that it's five feet tall, weighs 250 pounds, and will probably sell for $100,000. The invention was exhibited at the annual airshow in Wisconsin known as the EAA AirVenture, and is the product of 27 years of hard work on Martin's part. Originally tested on his wife and 15-year-old son (nice!), Martin's jetpack can hover for about thirty minutes, and has so far lifted a max of 6 feet off the ground. It comes complete with an emergency parachute, a shock-absorbent base and is weighted appropriately to prevent falling over. Here is Martin's website for more info, and some slowly-loading flight videos. more ›
