Just found a page from Air Pictorial I stuck in a scrap book. The air show began at 1000hrs on 5th May 1980. I flew from Biggin and landed at about 1004 in my Islander G-BDWG. The first aircraft to land at Croydon since it closed in September 1959.
I was to drop the Royal Artillery parachute team which was 'fun' since the runway was only 450yds long. I got off OK - the landing was much easier!
