LONDON — A blimp-shaped, helium-filled airship considered the world’s largest aircraft flew for the first time Wednesday with a short but historic jaunt over an airfield in central England.

Engines roaring, the 302-foot Airlander 10 rose slowly into the air from Cardington airfield, 45 miles north of London.

A hybrid of blimp, helicopter and airplane, it can stay aloft for days at a time and has been nicknamed the “flying bum” because of its bulbous front end.

The stately aircraft performed a circuit of the area – watched by hundreds of people who had parked their cars around the perimeter of the airfield – before touching down about half an hour later as dusk fell.

The Airlander is designed to use less fuel than a plane, but carry heavier loads than conventional airships. Its developer, Hybrid Air Vehicles, says it can reach 16,000 feet, travel at up to 90 mph and stay aloft for up to two weeks.

“It’s a combination of an aircraft that has parts of normal fixed-wing aircraft, it’s got helicopter, it’s got airship,” said chief executive Stephen McGlennan.
