The world's longest/largest aircraft is set to take its first test flight in a few days’ time. The unique aerodynamic balloon-like shape of the Airlander 10 - which cost $100 million (£60m) to build - can fly for five days straight, carry around 10-tons of cargo and land on water. Measuring 302ft (92m) in length, the new airship is about 60ft longer than the biggest airliners, the Airbus A380 and Boeing 747-8. It generates lift through being filled with helium and it can travel at a top speed of 92mph. In measurement, the plane is the length of a football pitch and as high as SIX double decker buses. The aircraft designers are rumoured to be planning an even bigger version that will eventually be able to carry 50 tonnes at a time. See more photos after the cut.
