As much as it was an awful thing to have happened, I think it made for absolutely spectacular television and I'm glad it's being televised again for the world to see. We love to see that sort of stuff on TV - who doesn't go "Ooooh!" when a plane goes down at an air show, or there's a spectacular car crash at the Grand Prix and the like? As humans there's part of us that loves to see destruction on TV, as long as we're not reminded of how many people died. I'm sure not many will agree with me, though.
I saw "The Sum of All Fears" today, and I can see why some people were wary of it when it was released. I didn't realise until halfway through that I saw it on 11/9 (what's all this 9/11 rubbish, anyway? We're not American, we don't put the month before the day when we write the date!).
