For 20 years, a South Florida woman kept the letters children wrote to 9/11 first responders. They will now live on at the 9/11 museum in New York City.

The number of lives lost in the 9/11 attacks likely would have been higher had William Rodriguez not been one of five people to have this inside the North Tower of the World Trade Center.

Imagine coming into work one day like you normally do, but then later on, frantically embarking on a mission in which the success of it might result in your death.

Even while the massive cleanup effort was going on after the Twin Towers were destroyed in the Sept. 11, 2001 terrorist attacks, plans were being formulated as to what the replacement to the towers would look like.

Get your tissues handy, because the 9/11 Memorial & Museum is getting ready to host a touching tribute for family members of those who lost their lives in the Sept. 11, 2001 terrorist attacks.
