This show was on PBS tonight.

It was a rebroadcast of a Nova show entitled Why the Towers Fell.

It’s all about the WTC disaster and it has a lot of footage from it.

It’s almost two years since the event and while I was watching it all I could think about was how stupid it was for someone to do this. If they hadn’t had done it, I doubt we’d be in Afghanistan and Iraq today. How different things might be - I can’t even imagine.
