H Peacock,
Many thanks for the update to the Marham Canberra incident. With 4 on board, one had to have been on the Rhumbold seat, so even more remarkable that he survived. IIRC, the pilot broke both legs. One of the navs was badly burned/scarred as well from being dragged along with the wreckage, but eventually recovered enough to become an excellent F4 WSO on 92 Sqn.
