This is pretty chilling.  A man named Randy Scott was trapped inside the World Trade Center on 9/11, and before he died, he wrote a note to get help and threw it out an open window.  It said, quote, "84th floor.  West office.  12 people trapped."

Someone on the ground found it that day, right before the building collapsed.  Then it was passed around for 10 years until DNA was used to match a spot of blood on the note to Randy.

And last year, the note was finally given to his wife, Denise.  She's agreed to put the note in a museum at the 9/11 memorial.
