A few years back I went to the Jet Display at Kemble to find they were marking 40 years of the Gnat. Enquired at the marquee and on disclosing I had been a student on Aunty Betty's Funjet, was offered free admission. Ended up watching the then current Red Arrows, surrounded by former team members, and even a couple of former Yellowjacks. Fabulous experience , overhearing comments such as "No ? is six inches out of position". Memorable day.
