Thank you "Treads", appreciated, I first flew at Kidlington back in the 50's when it was grass, Oxford Aeroplane Club, with the white Tiger Moths, Oxford UAS silver Chipmunks, also home to Mew Gull Gp-AEXF, BAC Drone G-AEKV with the Carden Ford engine and the first Piper Tri Pacer G-AORO, oh happy days.
