Can't argue with that Jim, but if you whack a glider with a spam can then the chances are that all occupants will be deaded. I spent many years in the RAF and even with Mr Martin and Mr Bakers finest seats a remarkable number of young men failed to reach their dotage through mid airs. Just as I arrived at Coningsby in '74 on F4s the Sation Commander Gp Cpt Bluck clobbered a Pawnee at low level and finished up as pink mist. His Nav was to be married the week after.
