Hi everyone. Don't know if anyone can help me here but I remember as a child in the 1980's, possibly even late 70's, heading for a family holiday. We were driving along a main road near London - at least a dual carriageway but might have been a motorway - and seeing tails of light aircraft (possibly some twins, Navajo etc.?) peeping above the top of the roadside embankment. The embankment seemed very high but I was only little so it might not have been as big as I remember it. I've looked on google maps and can't see an airfield that close to a major road so I'm guessing it's been built on.
I vaguely recall my dad saying it was 'Watford Airport'. Although my dad did once tell me that the Wombles lived in Blaydon, so this must be taken with a pinch of salt.
