Step right up — you can now get your very own jetpack. That's right, a real, not-science-fiction-honest-to-goodness jetpack. New Zealander Glenn Martin has been working on perfecting his jetpack for 30 years, and in 1998 created the Martin Aircraft Company to develop and market his idea. Now, the jetpack has become a reality. The 200-horsepower, dual-propeller is designed to fly average-sized person for 48 km (30 miles) in 30 minutes on 18 liters (5 gallons) of gas. The newest model can also reach heights of 2,400 meters (about 1.5 miles). Price? $100,000. "They are a helluva lot of fun to fly," said Martin.
