I recall turning up at a Kemble airshow to find that they were marking the 40th Anniversary of the Gnat. I asked at the Gnat" enclosure if former students were included and was invited in. Watched the Reds of that year display in front of may former Arrows from the Gnat years, and when one of them said "Red ? is 6" out of position", he meant it. Also met several instructors from my Gnat course days. Gold plated memory.
