One word "chilling" !!
Al I have family in metro NYC, I understand where you are coming from.
As a teen I can remember the construction of the Twin Towers, it was a sight to see. Thru the years we made quite a few visits to what was known as "Windows on the World " in the north tower on the 106 and 107th floors. It was an elegant restaurant and bar/lounge. We heard some great jazz there as well. I'll never forget the first time I took my wife to the area, I had to tell her stop looking up at the building's height, they'll know your a tourist.
When the attack occurred I received an e-mail that the a plane had crashed into one of the towers. We all that it could have been a traffic helicopter or even a small plane, but never..........did I think the unthinkable.
