Wrong Airfield
I think it was 1959 during the 'Arc to Arc' competition when a French Air Force Vatour landed at RAF Kenley instead of Biggin.
Only a couple of minutes apart in Vatour time and after all it was a race,but sadly only half the runway length,so he trundled through a lightweight fence onto Kenley common.
Took off some days later after attention to the gear.
Possibly the only twin jet ever to land there,(or any jet even).
Could have been worse if he had got as far as Croydon !!!!
