Forms 540 are not necessarily always accurate as the one mentioned above proves. Brian Gardner was not a Victor AARI but a Vulcan pilot and 9 Sqn captain. He was the third pilot and Chris Lackman (now deceased - see the thread on the Abingdon air show accident) was the crew's co-pilot. This 50 Sqn crew was the only crew that flew without an AARI - and they flew 3 of the 6 Black Bucks.
