The world's largest aircraft, The Airlander 10, made a surprising crash-landing during its second test drive in London. While no one was hurt, this comes as a crushing loss to Hybrid Air Vehicles, the company who sponsored the aircraft. Like a blimp, The Airlander 10 was made of light weight material and filled with helium, and was capable of speeds of 80 knots. With frontal damage, the company plans on fixing the aircraft and to continue making improvements on the air vehicle of the future.
