The world's largest aircraft had some safety issues. In 2016, the giant airship crashed into a telegraph pole and nosedived on its second test flight. In 2017, Airlander 10 collapsed before take-off less than 24-hours after a successful test flight. Two people suffered minor injuries.
Following that, the giant airship has completed six successful test flights, but it will need to complete a total of 200 incident-free hours in the sky before it is allowed to take on commercial passengers.
