for help, three girls dialing 911 while trapped inside an elevator shaft, the girls lying down on the ground as the elevator car comes within inches of crushing them. take a listen: >> [screaming and yelling] >> hello? >> lift it up, lift it up, please lift it up! >> help us. >> hello? >> where are you? >> we're in an elevator. >> i'm sorry? >> hello. >> we're trapped under an elevator at coffman -- at classon sas high school. heather: the doors opened and let them directly into the shaft which they first at thought was the elevator itself. it took about 45 minutes before the girls were finally rescued. one thinks that her boot may have prevented the elevator from coming all the way down. two of the girls are suffering from minor injuries. yeah that, one girl, she was wearing steel-toed boots.
