I was flying Whirlwinds at Manston '65-68 and flew the Chipmunks part time. I have WG 896, WG 837, WG 536, WP 627, WP 855, WD 344, WP 827, WP 846 & WP 837.
I was on shift when all the Heinkel's and Me 109's appeared. A bit startling as no one had bothered to tell us that they were coming. Suddenly the sound of all those Merlins - marvellous.
