Correct - the 747 on 4 November 1984 was G-AWND with the "Spirit of Yorkshire" name applied for the day. An all-LBA flight crew, with Mike Webster as Captain, Roger Greaves as F/O (whose dad instructed at Yorkshire Light for many years) and Barry Townley-Freeman (from Otley) as F/E. [Coincidentally, Roger and Barry were flying together on the BA9 volcanic ash four-engine flame-out incident with Captain Eric Moody in 1982.] Most of the cabin crew on the Yorkshire Post charters in November 1984 were also local, many of whom also worked in the BA Travel Shops in Leeds and Bradford at the time.
The aircraft which came later for the filming in the new Landor BA livery (probably 12 months afterwards) was G-AWNO and it was indeed Mike Webster flying. They were supposed to be going to Prestwick but the weather wasn't suitable so LBA it was.
After retiring from BA (the age for that being 55 at the time) then I also seem to remember Mike Webster arrived in a UAE 747SP for some crew training at LBA one day?
