Don't remember the BAC1-11 staging through Sharjah, and I was there at the time. But do remember a Lebanese/Middle Eastern airlines aircraft lobbing in enroute Lebanon-Mombasa or coming back that was broken. We Linies sorted it, and later a freebee ticket to Beirut was raffled off. I won the ticket, but declined the trip as it was only for the airfare - no accommodation included. Beirut was pretty pricey place to stay at the time, well out of Cpl Tech's pay packet.
