Lots of different descriptions around this story: "Damaged during flight"..."has been damaged after nosediving on landing"..."damage to its cockpit when it hit the ground"..."Collided with the ground"

But only one honest: "The Air Accidents Investigation Branch has confirmed it is investigating the crash"

It crashed. During flight it collided with a fixed object (technically an "ollision") resulting in damage to the aircraft. On its second a test flight, the experimental aircraft crashed.
