Cavern City Air Terminal (ICAO: KCNMFAA LID: CNM) is a public use airport in Eddy County, New Mexico, United States.[1] It is owned by the city of Carlsbad and located five nautical miles (6 mi, 9 km) southwest of its central business district.[1] The airport is served by one commercial airline, with scheduled passenger service subsidized by the Essential Air Service program.

As per Federal Aviation Administration records, the airport had 2,207 passenger boardings (enplanements) in calendar year 2008,[2] 3,417 enplanements in 2009, and 2,606 in 2010.[3] It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility (the commercial service category requires at least 2,500 enplanements per year).[4]


AAF Bombardier School patch, 1943

Established by the United States Army Air Corps in 1942 as Carlsbad Army Airfield, the facility was activated on October 12, 1942. Assigned to United States Army Air Forces West Coast Training Center (later Western Training Command) as an advanced (level 3) twin-engine training airfield. Began training flying cadets under the 940th Two-Engine Flying Training Detachment. Had a local axillary airfield for emergency and overflow landings.

The twin-engine school was replaced by Bombardier's School in mid-1942. Bombardier school lasted from 12 to 18 weeks during which a student dropped approximately 160 bombs, both in daytime and at night. Precise records were maintained of his hits and misses; the elimination rate was 12%. Upon graduation, a bombardier was transferred to an operational Second or Third Air Force training unit to join a crew being trained for overseas duty. The bombardier trainer used was the Beech AT-11 Kansan.

Inactivated on September 30, 1945 at the end of World War II and turned over to the Army Corps of Engineers. Eventually discharged to the War Assets Administration (WAA) and became a civil airport.
