Speculation that winch launch commenced with elevator not connected.

Which would perhaps lead to a steep climb, stall/spin and rotation in a near vertical attitude resulting in an inverted impact, usually fatal. Happened on auto launch in Georgia several years ago with an all-flying tail stall on a Phoebus C. Pilot hurt but survived.

Recognized hazard in winch launching whatever the cause. Like all accidents, preventable.
