When I say "crashes", I should probably say "does a slow-motion pratfall" - but that's too long for a blog post title. The aircraft in question, the Airlander 10, is essentially a large, modern hybrid blimp and is filled with helium.
The aircraft was not traveling very fast and maneuvers slowly anyway and so it sort of slowly crunched into the ground. No one was seriously hurt during all this. The first flight had gone well, but this is why they are called "test flights".
