that video is rather bleak!
FWIW those who were in BA in 1990
will tell you that their colleagues who were portrayed in "that video" were almost all, with good reason, well and truely ***** off at the way their contribution was edited to create a certain impression (one of the captains involved even felt the need to apologise to his colleagues in print).
Those who have been around during the filming of the current video may be able tell stories of selective small sections of the "staff only" portions of T5 being repainted and dressed to create a nice backdrop to some of the scenes.............
Watch it by all means but treat it and the impression it creates with a great deal of caution.......
