(Interestingly, I think it was at Duxford but I'm not sure, I once had a controller - or it must have been an AFISO if it was Duxford - ask me to confirm that my gear was down. I checked, and it was... and I realised that the unusual gear arrangement would probably confuse anyone who was looking at the aircraft and didn't know what they were looking for - they would probably not see enough wheels, and even if they knew how many wheels to look for, the top of the main wheel remains inside the wheel well when the gear is extended, so it probably looks like it's up when it's not if you're not close to it.)
