I live quite close to Wisley Airfield in Surrey, UK, which lies just south of the A3 road close to Junction 10 of the M25. Wisley Gardens (Royal Botanical Society) is just to the north of the A3 at the same point. The airfield was used in conjunction with the Vickers/BAe aircraft factory at Brooklands and was in use for flying until the early 1970s. Since then it has lain dormant except for the occasional bus rally and cow-pie show. It is now controversial as developers wish to build a 'new town' there, much to the outrage of existing local inhabitants although the new Labour government might well over-rule their objections.
However, with the M25 Junction 10 upgrade works that are currently making our lives rather difficult in this area, there has been some attention to the airfield which is partly being used as a works depot for the upgrade. In a recent very interesting YouTube video about the history of the airfield, it was mentioned that Wisley had been known as London Race Park and used for motor racing. This came as complete news to me - despite being born and raised in the vicinity, I had never heard of any motor sport usage for the airfield. A bit of Googling revealed just one Reddit post that said it was used for a F3 race in 1966 which may have been where the YouTube video got the story.
But I wonder if this is true as this list of British 1966 F3 races makes no mention of a race there, nor can I see any other record. Is this just someone's fantasy race track design or is there any substance to it? I note that the text claims that it was "..was massively used for testing of Le-Mans spec sports cars of that era."
Can anyone cast any light on this or have I been led down a rabbit-hole? And is this how fake news becomes "fact"?
