I was there, i saw it happen. I went to the airport with the kids to watch the airplanes from the panorama terrace. At around 5 pm the airplane involved approached the threshold of runway 22 at a 90 degree angle.
A sort of threshold base, exept that it was flying at 100 feet...(!!!) it required a ninety degree turn to the right to end up on the runway. This turn was executed at around 50 feet, with initially 30 degrees bank. As the aircraft progressed through the turn, its bank angle suddenly increased to about 60 degrees and it slammed onto the runway. Right wing first.
Airspeed was low during the entire maneuvre, around 80kts.
Immediately one of the occupants exited the aircraft wreckage.
Crashtenders were there within 2 minutes.
