As a young SAC I remember going from Akrotiri on a Kingsfield det to accept a couple of Hercs over a few days in 1977. The gear at Dhekelia had been there for a long time so when I towed a GPU across the runway, (with clearance), the brakes were binding so my tow was slow. Shock and horror to look out the window to see a Herc on finals! Dunlop written backwards on the roof was close :-)
