Mmmmmm.
The pilot was Jack Henderson not Clive. After a roller landing Jack felt a marked jolt and it transpired the left leg had displaced 80deg left. Since part of a ground loop was clearly on the cards we were all concerned that the aircraft would roll RIGHT as it slewed LEFT and perhaps ding Jack by going inverted. After touchdown the aircraft actually turned left through about 120 deg but did not roll right.
