Company 1 dispatched to a MVA with entrapment to 460 bypass eastbound.  Engine 1-2 arrived on scene with 107 (Sgt. Thompson) in command with a one vehicle MVA rollover on the left side of the highway.  PEVRS provided patient care while Engine 1-2 crews assisted Rescue 1 with the extrication as well as provided an LZ for the 2 Med Flight helicopters.  With both patients being turned over to Med Flight and the wrecker service having possession of the vehicle the scene was under control and command was terminated and Engine 1-2 returned to service.
