GASTON, Ore. -- Two people were rescued after the car they were in was pinned underneath an estimated 15,000-pound tractor for nearly two hours Wednesday night in Gaston.

Victor J. Accomando, 73, and Donna C. Accomando, 62, of Beaverton survived the crash and were airlifted to Legacy Emanuel hospital. They were listed in serious condition Thursday morning.

Two farm tractors pulling combine trailers were southbound on Highway 47 (Front Street in Gaston) about 8:30 p.m. when the northbound 2006 Pontiac Solstice clipped the combine trailer behind the first tractor near Main Street.

That pulled the car into the path of the second tractor, which drove onto the Pontiac and came to a rest, according to the Washington County sheriff's office.

Crews on scene provided medical aid to the couple while working to lift the tractor off the car. As a crowd gathered, two big tow trucks were used to raise the tractor, with wood blocks placed under it as it was lifted.

The couple was finally freed shortly before 10:30 p.m.

The tractor drivers, age 15 and 17, had valid licenses to operate the farm equipment.
