His name is Steve Johnson, but you were close. The Reds were operating from Biggin and Steve returned there later the same day apparently none the worse for wear. Mind you, he may have had a bad head the following morning!
... and a very pleasant chap he is to. Retired from BA a couple of years ago. He told me his first thought as he heard the bang was that he'd hit his mate coming the other way. He was in a dinghy fairly shortly afterwards!
