I do the same. Anytime they play any of the footage from that day we weep at this house.The closest we were to things that day was Flight 93 since we are on the flight path of the airports here.
Windows on the World was a wonderful place...Decent food..but the view..unreal...you could look out at the jets flying BELOW your eye level heading into LaGuardia..
Probably ate there 50 times since the Towers opened. All special occasions, very happy memories..
