In the good old days, RAF North Weald was on the Central Line. Not that such a thing would have much appeal for rich-bitch bizjet cargoes, I guess....
But many an RAF pilot would fly to North Weald, then head off to the Smoke on the Central Line.
In his book 'Meteor EJECT!', Nick Carter describes how he was called at Chivenor one day and told to be at the Air Ministry at 11:00 the following morning:
Next day I flew a Hunter up to North Weald, changed and caught the tube into London, arriving at the Air Ministry in plenty of time for a cup of coffee before being escorted along the corridors of power.....
...On the way back to Chivenor, I did a small detour and did a couple of slow rolls over my home in Maidenhead for old times' sake.
The things one could do back in 1958, in the days when we had a real Air Force!
