The accidents usually occur when steep turns and/or steep climbing turn
exits to the pass are attempted with pilot distraction outside the
airplane to objects or persons on the ground. The stall speed increases
as g is applied and too hard a pull accelerates the stall. In many cases
expert pilot witnesses to these accidents testify to a noticeable slip
or skid just before the stall which would indicate an off center ball
due to pilot distraction outside the airplane.

Another factor may be the good old inner ear lying again - with the head
turned rapidly to watch the subject of a buzzjob followed by the pullup
whilst still concentrating on the ground may lead to the situation where
the pilot doesn't realise the lack of coordination and pitch attitude.

The flight medical guy who did a talk at our club described it -
unfortunately it's too long ago to remember exactly how he described it!
