The Airlander 10, the world's largest aircraft, combines the latest in technology and engineering to dwarf everything else in the skies at 300 feet long by 140 feet wide. This marvel can stay airborne for five days crewed or up to three weeks unmanned and land anywhere in the world, whether on land or at sea. It's a hybrid aircraft with the best features of normal aircraft, helicopters, and, of course, airships. With no internal structure, the Airlander maintains its shape due to the pressure stabilization of the helium (1.34 million cubic feet) inside the hull, and the smart and strong Vectran material of which it's made. With a payload capacity up to 11 tons, it can cruise up to 100 miles per hour. On 17 August 2016, the first test flight took place at the aircraft's home base, Cardington Airfield in Bedfordshire, England, and lasted 30 minutes.
