Bullet 580 Blimp Is The World's Largest Airship—Which You Can HireS

Costing $8 million, the Bullet 580 is the world's largest blimp, measuring 71m long, and 19m in diameter. Able to be flown remotely or with a crew, you could rent it—for over $300,000 a month.

If you do decide to rent it out for a month, you've got a long time of inflating ahead of you—it took six hours to inflate it with helium at Alabama's Garret Coliseum, where this picture was taken. Built from kevlar material which is ten times stronger than steel, the blimp can hold up to 2,000lbs of weight and travel 6,096m (20,000 feet) high, traveling at 35mph with a top speed of 80mph.

While it'll be available to rent out at a later date, its first test flights will only occur this summer—so there's no promises you'll be flying over the Grand Canyon this Christmas. [E-Green Technologies via The Age]
