VIDEOS: A three-alarm fire tore through a Catholic school in Philadelphia's Chestnut Hill neighborhood on Tuesday afternoon. The flames broke out around 3:45 p.m. at the Our Mother of Consolation School located on East Chestnut Hill Avenue. Chopper 6 was overhead as heavy fire consumed the attic, roof and classrooms. The blaze was so intense that it caused the roof to collapse. "It quickly became apparent the fire was deeply embedded in the building, so we had to evacuate the building to prevent our members from being injured in collapsing structure components," said Philadelphia Fire Commissioner Adam Thiel. Chopper 6 was live over a raging fire at Our Mother of Consolation School in the Chestnut Hill section of Philadelphia. It took about 120 firefighters to get the blaze under control just after 5 p.m.
