The world's largest aircraft is set to take to the skies for the first time. It's called the "Airlander 10” and has been developed by British aviation experts. The 92-meter-long aircraft will have its test-flight in just a few weeks. The innovation is a mix between a plane and a helicopter that uses the absolute latest materials and technology. It can fly for five days without refueling and stay floating. What’s more, it's filled with helium to help keep it in the air. Plus, it could carry around 10-tons of cargo and 48 passengers and can take off and land on almost any surface including water, ice and desert. So it will be useful for cargo and hard-reached places.
