Today the prototype Airlander 10 undertook its second test flight and flew for 100 minutes, completing all the planned tasks before returning to Cardington to land. The Airlander experienced a heavy landing and the front of the flight deck has sustained some damage which is currently being assessed. Both pilots and the ground crew are safe and well and the aircraft is secured and stable at its normal mooring location. Hybrid Air Vehicles runs a robust set of procedures for flight test activities and investigation of issues. We will be running through these in the days ahead as we continue the development of the Airlander aircraft. Further updates will follow in due course.
