The photo above of the 747 in the new livery was the event you are talking about LS27 and I am fairly certain it was the last BA 747 into LBA. The local pilot was Captain Mike Webster, from Roundhay, who flew the original BA 747, Spirit of Yorkshire, into the airport on 4th November 1985 (G-AWND). He also flew in 747s in the livery of United Arab Emirates and Air Hong Kong. On the day he also flew the 747 over to Roundhay Park and carried out around 6 circuits of the park at low level. I was grateful for this as I was there playing golf. It did little for my round as I totally lost concentration. I have never been so surprised as I was when I saw the 747 cruising at low level down the Ring Road.
For anyone not aware, G-AWND was destroyed on the ground having been caught on the ground in the Middle East during military coup. A sad end to the first 747 to land at LBA.
