I remember hearing a psychologist talking on the radio not long after this tragedy, and he said that the constant re-playing of the crash images on TV was not only not at all helpful to anyone watching, but was subtly psychologically damaging - and that is a view i have held from then until now - i avoid any programme like this which re-hashes recent history. It adds absolutly nothing to my sense of horror and grief, but merely rakes over the images once again, to no good purpose at all.
Cruising on the QM2, my wife and i dined with a couple who live two streets away from the Towers, and had gone to vote in a school poling station across the road at the time the planes hit.
The gentleman of couple trained navy seals in his career, so was obviously no-one's softy, but as he recounted what he had seen, silent tears leaked out of his eyes. When he excused himself to go and compose himself again, his wife confiemed that he was so traumatised, that after a few weeks, he was forced to walk with a cane to support a limp. The doctors advised that there was nothing physically wrong with him, the limp was a psychosomatic reaction to the trauma, and was therefore untreatable.
That's as close to the impact of this tragedy as I ever want to be, and watching this type of documentary is something I would avoid like the plague.
