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 !!!!
There's a little more on this at
http://jiscmediahub.ac.uk/mediaConte..._EE_02_ITV.pdf which indicates that it happened in July 1959; it even gives the name of the Lady concerned - apparently a 'model', but no mention of any WW2 exploits.
And a small picture of the aircraft at Kenley (well, nearly Kenley!) on the front-page of a French newspaper; see
