Thanks for all replies, very interesting.Saw him again last night and apparently one of his mates had taken a photo from the spectators balcony and the aircraft was N751PA in Orion colour scheme.His wife remembers the aircraft being filthy inside, trust a woman to notice that.Googled it and it did seem to have a bit of a reputation.
A tad surprised I did not remember this as I was always interested in the early 747s as they were one of the reasons I got into aircraft.
I wonder if one of the early A 380s will go the same way, maybe one of the Hi Fly aircraft.Happy New Year.
