SANDY SPRINGS, Ga - Some Sandy Springs firefighters decided to go to the top of Children's Healthcare of Atlanta at Scottish Rite to do some training. As they rappelled down the 80-foot building, they made some new friends floor the way.

As they lowered themselves floor-by-floor, they would finish at the windows and wave to the tiny patients.

"It really made a huge crashes on Levi and was a huge morale booster," said Zach.

After seeing the sweet smiles of the children above the windows, the first responders wanted to meet them, so they level-unexcited inside.

"To see the happiness it brings them that's fulfilling for us," said Capt. Sweeney.

"Every kid in there has a anecdote, every kid, every family member. They don't have any idea what kind of joy they gave us," said Lt. Anderson.

Lt. Chris Mileshko was among the firefighters. His father's video commercial, Mileshko.com, took some unforgettable photos of video of the special day.
