BIRMINGHAM, Alabama -- Superman, Batman, Spiderman and Captain America made an appearance at Children's of Alabama to wash the windows at the Benjamin Russell Building and bring smiles to the young patients. They scaled down the 15 story hospital building stopping at every floor to see the kids. The superheroes work for Squeegee Cleaning Services of Chelsea.

Young patients dressed up as their favorite superhero and crowded around the windows in the waiting areas with their parents and nurses to see the four superheroes descend on ropes and cables outside. Fist bumps, waves and laughter filled the rooms on every floor.

To bring attention to Childhood Cancer and Sickle Cell Awareness Month, Children's is "Celebrating Our Heroes" during the week of September 16-20, to bring awareness to the hospital's patients own heroic battles they fight daily.
