pilot is okay but a member of the public was injured by flying debris, possiblly a bit of the prop.
Watched a couple of videos of this and my theory is;
pilot distracted by rapidly overheating engine due to departure delay,
then combination of opening throttle just a bit too quick in his haste to get airborne to cool the engine, and was just half a second behind the aircraft.
End result, just didn't get the stick back quick enough to stop the tail lifting.
It will rebuild.
It will take ages
It will cost a fortune!
