Percivals Aircraft club house in Luton was located at Castle Street. The site is now a car park where the inner ring road cuts through to Stuart Street.
The sports and social club also organized most of the inter office and inter departmental sports championships, as well as the annual outdoor Field Day. This was a family affair, with competitive sports for all ages. Track and Field events were surrounded by carnival booths, including Punch and Judy shows, rifle (.22) targets and sideshows. It was during the 1945 Field Day that the remains of Capt Percivals famous Mew Gull was burnt.
Info quoted from the book Percivals Aircraft by Norman H Ellison
According to
https://books.google.co.uk/books?id=...G-ACND&f=false G-AFAA was actually burnt in 1946 as a fire-fighting exercise by Luton Fire Brigade.
Also here
https://en.wikipedia.org/wiki/Percival_Mew_Gull that G-ACND was burned at the same time as G-AFAA at the Field Day in 1945 so someone is wrong here.
G-AFAA
The one-off Type E.3H (the so-called "Super"-Mew ) was Edgar Percival's personal mount. While looking very much the same as the E2H, this was actually a completely new design, powered by a Gipsy Six Series II. It first flew in 1937 and was raced by Percival in 1937–1939. On loan for propeller trials at Hatfield during the war, G-AFAA was written off in a landing accident by a de Havilland pilot. The remains of this aircraft were burned with those of G-ACND at a Percival Aircraft garden fete at Luton Airport immediately after the war.
