The Flaps
The PNF retracted the flaps at 22.16.37, the airplane was 90 degrees to vertical at that time and the pilot was applying left aileron, airspeed was 98. The PNF did what she could to save the situation uncommanded, gear and flaps up. Actually if they had been about 1000 feet higher they would have recovered - at 22:16:43 the airplane was straight and level at 129 knots. Which explains the witness reports that the airplane was headed away from the airport.
