I often think about this and always come up with something better and better (in my mind, that is)
My latest thought about this is that the City of NY should hire the people from Disney, (don't laugh) to create a "Back to September 11, 2001" kind of a walking display tour, that will start with pictures or movies of what was going on just before the first plane hit the WTC, and then as you move forward ... you can see a plane in the sky and then "BOOM", feel the flash, the heat, the vibration and hear the cries of people. Next, continue to show everything that happened that day, the fire trucks rushing to what will be their last call, the policemen trying in vain to control the sea of people rushing from the buildings, the flames and smoke coming out of the buildings, and yes ... the people waving out of the windows crying for help, and them jumping out when the heat was too much. I would like the people to see the firemen walking those endless steps, and then the buildings collapsing and aftermath including the radio's transmitions to nowhere, the beeping sounds from the fireman's distress boxes, the people walking on the bridges out of NYC, etc. etc. Then they MUST show how this country came together, how everybody was flying, displaying and wearing an American flag, (if you were lucky enough to find one) and how we were all united as ONE, for once.
Do you remember?
