A small airplane crashed in trees Tuesday in a federal wildlife refuge in Anne Arundel County, Md., coming to rest about 50 feet above ground, authorities said.

The occupants of the single engine Socata Tampico were identified by the state police as pilot Thomas Falk, 55, of Silver Spring, and James Palazak, 59, of Columbia.

Both were taken to a hospital but neither appeared to be seriously injured, according to the county fire department.

Capt. Russ Davies, a spokesman for the county fire department, said one of the occupants was brought down on a ladder, and the other by ropes.

State police said that the reasons for the crash had not been determined, but that prelimination investigation indicated possible engine failure. The crash occurred about 6 p.m. at the Patuxent Wildlife Refuge, near Route 198 and Bald Eagle Drive authorities said.

The site was near Tipton Airport, a general aviation field.
