The one I will always remember was the card with a drawing of the Trade Center Towers on each side. In between was a heart. Underneath was a message written in a child's hand:
Thank You For Saving Everyone
In many cases, of course, these heroes and heroines physically rescued no one. The leading group that went up the stairs of the second tower that was hit (the first tower to fall) all perished before they could lead any one out. There was no time. Two made it up to the 78th floor elevator waiting area where the second plane had plowed directly through a crowd. There they reported back on what they saw and comforted the shocked, injured and dying in the few minutes they all had left.
Just because they all died doesn't mean that that the above words weren't--at least partially--true.
