Gray Army Airfield
Gray Army Airfield , also known as Gray AAF, is a military airfield located within Joint Base Lewis-McChord (formerly Fort Lewis) near Tacoma, in Pierce County, Washington, United States.〔
It should not be confused with Robert Gray Army Airfield at Fort Hood in Texas.
== Overview ==
Used to support Fort Lewis, Army helicopters assisted with medical evacuations at Mount Rainier National Park on numerous occasions in the 1970s. Army helicopters were also used to insert search-and-rescue () teams into inaccessible areas on the east, north, and west sides of the mountain, lowering rangers to the ground by a cable device known as a "jungle penetrator." Helicopters began assisting with high altitude (above 10,000 feet) SAR operations in the 1980s. Helicopters were also used for "short haul" rescue operations, in which a ranger and litter were carried in a sling below the helicopter to the scene of the accident.
