VIDEO: Chopper 6 was over a dramatic crash rescue that unfolded in Chester County on Tuesday.
Firefighters responded to a collision on the 400 block of Hilltop Road in Tredyffrin Township just after 10:30 a.m.
Authorities say a man had been trapped under a red SUV for at least 30 minutes before he was freed.
It's something firefighters weren't sure would happen.
"You're expecting the worst, obviously. A car is on top of a patient, the entire car was covering the body," recalled Captain Bob Robie with the Paoli Fire Department.
Action News has learned that the driver of the vehicle was backing down a steep driveway after dropping someone off.
As he was backing up, investigators say his tires went into the grass, so he opened the door and leaned out to get a closer look.
When the driver was leaning out of the car, however, he was pulled under, police say.
