LONDON (AP) — 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 (92-meter) Airlander 10 rose slowly into the air from Cardington airfield, 45 miles (73 kilometers) 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.
