Since the 1850s, engineers have been experimenting with powered lighter-than-air flight, essentially balloons with steering and propulsion. Like other early aeronautical experiments, the trial-and-error period was lengthy and hazardous. Dirigibles (with internal support structures) and blimps (powered balloons) were filled with lifting gases like hydrogen or helium, intended for many uses, from military and research to long-distance passenger service. The growth of the airship suffered numerous setbacks, including the famous Hindenburg disaster in 1937, and never developed into a major mode of travel. Despite the challenges, more than 150 years later, a number of airships are still in use and development around the world as cargo carriers, military platforms, promotional vehicles, and more.

The German-built zeppelin Hindenburg trundles into the U.S. Navy hangar, its nose hooked to the mobile mooring tower, at Lakehurst, New Jersey, on May 9, 1936. The rigid airship had just set a record for its first north Atlantic crossing, the first leg of ten scheduled round trips between Germany and America. (AP Photo)

The German dirigible Hindenburg crashes to earth, tail first, in flaming ruins after exploding at the U.S. Naval Station in Lakehurst, New Jersey, on May 6, 1937. The disaster, which killed 36 people after a 60-hour transatlantic flight from Germany, ended regular passenger service by the lighter-than-air airships. (AP Photo/Murray Becker)

The wreckage of the naval dirigible USS Akron is brought to the surface of the ocean off the coast of New Jersey, on April 23, 1933. The Akron went down in a violent storm off the New Jersey coast. The disaster claimed 73 lives, more than twice as many as the crash of the Hindenburg. The USS Akron, a 785-foot dirigible, was in its third year of flight when a violent storm sent it crashing tail-first into the Atlantic Ocean shortly after midnight on April 4, 1933. (AP Photo)

At a Nevada nuclear test site test Site, on August 7, 1957, the tail of a U.S. Navy Blimp is photographed with the cloud of a nuclear blast in the background. The Blimp was in temporary free flight in excess of five miles from ground zero when it collapsed from the shock wave of the blast. The airship was unmanned and was used in military effects experiments. Navy personnel on the ground in the vicinity of the experimental area were unhurt. (National Nuclear Security Administration)

Rousson failed in an earlier attempt to make the 34-mile (55km) journey across the English Chanel in a pedal powered airship. On his second attempt, he made it only halfway before deciding to give up. (Peter Macdiarmid/Getty Images)

Bradley Hasemeyer uses his smartphone to photograph the Aeroscraft airship, a high-tech prototype airship, outside a World War II-era hangar in Tustin, California, on January 24, 2013. Work is almost done on the 230-foot rigid airship prototype inside the blimp hangar in Orange County. The huge cargo-carrying airship has shiny aluminum skin and a rigid, 230-foot aluminum and carbon fiber skeleton. The prototype is half the size of the planned full-scale version, which will be designed to carry up to 250 tons of cargo.(AP Photo/Jae C. Hong)
