The clip wasn't just about the human cost of just those on board:
it was to emphasise the link to the cost to the population of a large chunk of Britain that then had accept major social change as part of the “peace” process (I do not want to discuss “the end justifies the means” here);
it was to hammer home the motive for a possibly contrived crash;
it was to let you look into the faces of the people that the service that you were so proud to serve in let down, both at a high level before the act and insidiously down through the ranks afterwards when people who knew of the equipment and its uses did not bring it to the attention of the inquiries.
