“Tower Of Heroes” shares the inspirational stories behind the annual Tunnel To Towers Tower Climb New York City, which will challenge more than a thousand climbers to scale 104 stories, 2,226 steps to the observatory at the top of One World Trade Center on Sunday, June 7. Each step taken during the climb is a reflection of the extraordinary support The Tunnel to Towers Foundation provides to catastrophically injured Veterans and first responders, Gold Star families, and families of fallen first responders for almost 25 years. This year, the special holds special meaning as it honors the 25th anniversary of September 11th.
