Me being hypocritcal now, inrespect of my last post. Several SR71 displays, including one where the pilot tried to light the afterburners whilst in a fairly high 'g' turn. The fuel did not immediately ignite, but did shortly afterwards, contributing to what were regarded as the best 'photos of the Blackbird ever, with two very large fireballs pursueing the aircraft, but I am sure someone on here will post the pictures. I have it on video,
