Squad 65 was dispatched at 1850hours to assist Bucks Station 57/75 on a vehicle rescue on Rt. 663 and Kumry Road.  The Squad with 5 responded and arrived within 3 minutes of dispatch and found a 2 vehicle crash with one heavily entrapped.  57/75 crews went to work with stabilization and patient care while Squad 65 crews went to work with a roof removal, driver side removal and a front end roll.  With severe damage to the drivers side, crews had to peel away mangled sheet metal to expose the cut points.  Crews work for about 20 minutes to free the trapped subject.  Patient care was turned over to EMS and then to a Med-e-vac helicopter.  Crews cleared the scene in about 45 minutes but didn't return to service for another 30.  Fire Police assisted with Traffic 65 to detour traffic around the heavily travelled Route 663.
