Ah, a memory moment. Having hosted a Hull ATC Squadron around Local Control (the greenhouse bit on top of the Air Traffic Control building) circa 1982, it became apparent that certain items had 'gone walkabout'. Namely 1 Very Pistol and 5 Very Pistol Flare Cartridges. Thankfully, someone twigged that Local Control was slightly 'deficient' in inventory items and the 'little tinkers' of Hull ATC were given a shake down before leaving Air Traffic. The result produced the Very Pistol but also SIX Very Cartridges. We were missing 5. A quick demonstration to the Humber 'Little Tinkers' by blatting off a Red, solved our accounting problem. But.......where had the 'Little Tinkers' aquired the extra Cartridge? We locked the ground floor door, played Uckers (Thank You RNEFTS), and promptly dismissed the whole thing.
