In 1970 as a youngster, I saw from the Queens Building the first of these beautiful aircraft at Heathrow in BOAC colours.
I seem to recall that the first 3 741s (G-AWNA, B and C) were parked up on the BOAC maintenance area for months because of wrangles between BALPA and BOAC. The good old 1970s!! At least in those days enthusiasts had somewhere in the central area of LHR where they were welcome. I know it's a changed world, securitywise, but it's such a shame that our young grand kids can't any longer get up close and personal with aircraft in a sanctioned public area at many of our airports.
