Winchester June 1989. Day before actual passout parade during final practice. The right hand marker a tall chap monikered after a yellow ornithological creature from an American kids programme was stood at attention. It was a very hot day (June) he fainted and fell forward still in the position of attention. Ramrod staright all the way down. His SA80 was still vertical as he was horizontal. Poor chap smacked the tarmac with some force. Thankfully he was okay but sadly didnt pass out the following day. He did go on to have a career and is still in I believe.
