Great challenge thanks.
And there was me thinking the road was A36, and started looking for aircraft type rather than reg.
The Gash bus company gave me the best clue, so was a bit lucky as I only found the Bowbridge Road depot and then used Google Earth to find the nearest airfield.
Is the Vulcan still there?
I regret to announce it's open house as I'm not at home.
Help yourselves guys.
