I agree to, I always get very nostalgic when I see photos of that particular BEA livery especially as you to the bland BA scheme that followed.
Although I have no personal photos to post I have vivid memories of overlooking the apron at LHR Terminal 1 in the early 1970's with Tridents and Viscounts in that beautiful BEA scheme along with Cambrian BAC 1-11's, Viscounts, Northeast Tridents and Viscounts and B737's of Aer Lingus in their retro 60's livery.
My first ever flight (in first class to) was on a BEA Trident 3 LHR to DUS in July 1972 three weeks after the Staines crash, was I nervous about that fact I wasn't but I remember my mother being worried.
