OK, its not at an airfield but I remember a 24 hour transport cafe on the A5 between Cannock and Telford where one could pull in at 2am and get the best breakfast. I can taste it now, the bacon, sausage, tomatoes, black pudding, mushrooms, brown sauce, toast and a huge mug of tea for £4.
Oh, their bacon sarnies were out of this world at 2am. Especially the bacon, egg, black pudding and brown sauce variety. Magic!
