9/11 TV Coverage

am i the only person wondering why we are being shown coverage all this week of 9/11? 8 years later and it's still as haunting as ever. i tuned into BBC1 just after the first plane struck and witnessed it all from the comfort of my home in the UK, it was deeply disturbing and unforgettable, i don't need to see it on screen again to remember. i would like to think that the film and documentary makers were giving their profits to the victims' families and to those who survived but must still be wondering how come they were chosen to be the lucky ones.
