FLOATING INTO THE FUTURE!!!!!!!

The notion that airships represent the future of air cargo is being revived by a new generation of entrepreneurs some 75 years after a catastrophic fireball brought the industry to a screeching halt.

Far safer than the Hindenburg, whose tragic 1937 docking remains an icon of aerospace gone wrong, these modern airships are a hybrid of lighter-than-air and fixed-wing aircraft. They can loft enormous payloads without requiring the acres of tarmac or miles of roadway necessary for conventional air and truck transport. And they do so at a fraction of the fuel and cost of aircraft.

Airships "give you access and much larger payloads at much lower costs," said Peter DeRobertis, project leader for commercial hybrid air vehicles at Lockheed Martin's Aeronautics and Skunk Works division in Fort Worth, Texas. "It's also a green aircraft; you're not polluting."

Today's airships could conceivably be used to transport everything from ripe pineapples to heavy industrial equipment direct to the customer. Shippers, for example, could roll tractors, backhoes, and road graders onto a 50-ton hybrid vehicle at a factory and roll them off at the job site, easing logistics and cost.

A handful of companies have prototypes under development. Lockheed has an airship in the works dubbed SkyTug that should be commercially available by late 2013 with a range of 1,000 nautical miles and a 20-ton payload. The 50-ton Skyfreighter is expected to follow in late 2014.

The industry's future is initially aimed at leapfrogging the conventional cargo transport infrastructure, freighting goods where highways and airports don't exist - Canada's frozen north; China's western frontier; remote parts of Africa, Asia, and South America. No airships are commercially available for cargo transport there yet. But once established on the frontiers, experts say their versatility, cost and fuel advantages should allow airships to penetrate mature freight markets like the United States.

'Hard to justify any roads'

Optimistic entrepreneurs have made similar predictions before, however. Germany-based Cargolifter AG burned through some $500 million without building so much as a prototype before it went belly-up in 2002.

But today's technology is much improved from earlier, flawed approaches. And the potential market is vast.

In northern Canada, for instance, some 4 million square miles of real estate lie north of rail lines and all-weather highways, and warming winters are making seasonally-constructed ice roads less reliable. Historically, ice roads were open three months during the winter. Today, they barely see 30 days of operation per season.
