^I saw a documentary about that incident a few years ago, it was truly horrible. I know what you mean about the horror bringing out the humanity in people, though. For about 6 months after September 11th it felt as though everyone in NYC was your best friend. Their was a real kinship among the residents of the city that expressed itself very positively for a time.
Along the same lines - I was brought to tears after Hurricane Hugo in 1989 here in South Carolina when, amongst the truckloads of food and emergency supplies that were arriving, there was a truck of dog food and cat food. I was just very touched that some people out there hadn't forgotten our pets.
