Staying with Engineering Officers; RAF Leeming, circa 1968, Jet Provost 3’s and 4’s. I had just towed an aircraft from the maintenance hangar to a storage hangar and the route took me past the Engineering Officers office window. I get back to the maintenance hangar and a few minutes later I get called into the Chiefy’s (Chief Technician) office, He tells me to go back to the storage hangar and check the L/H main wheel tyre. “Why” I ask, Chiefy tells me, with a perfectly straight face, that he received a call from the Engineering Officer telling him that the L/H main wheel was not rotating as the aircraft was towed past his window. I was incredulous, nevertheless off I went, looked at the tyre, which of course was perfectly OK, went back and told Chiefy. Lots of knowing grins all around.
