Mind you, talking of customs at Brize, it was the custom (excuse the pun) that on most AT arrivals the crew were cleared customs onboard. The crew filled in the customs chit before landing, stating what they had or had not to declare, then the Captain countersigned. Before anyone was allowed off the aircraft the customs officer had to look at the form and clear the crew. Sometimes they would ask to see what the individual had imported. On one such occasion, the naughty co-pilot added an item to the declaration made by a brand new and rather naive young female steward. He wrote 'Sexual aid' and slipped into her handbag a suitable object. The customs official cleared the whole crew, but asked the young lady to see the said object. She went bright red and even brighter when opening her hardback to reveal what had be cruelly placed there. No, I was not that CO, just the Captain
