I drew up a list of what I could remember/find belonging to Doug Arnold/Warbirds of Great Britain/Fairoaks Aviation Services last night, blimey!
The P-40N is N9950 and there is indeed an FW190 wreck, looked fairly complete too. Google them, there are photos out there.
Nosing around the web last night, I saw that supposedly parts of the Jeddah A-26 were also at Biggin Hill along with the Lancaster/Lincoln parts stacked outside the hangar.
What happened to the orange Catalina which was at Biggin and moved to North Weald? Is that the one that was en-route to Israel and lost an engine in France?
