Context paragraphs:
Propulsion Wind Tunnel Facility: The Propulsion Wind Tunnel Facility, located at Arnold Engineering Development Complex, Arnold Air Force Base, Tennessee, holds three wind tunnels: the 16-foot transonic (16T), 16-foot supersonic (16S), and the aerodynamic 4-foot transonic (4T) tunnels.  The facility is devoted to aerodynamic and propulsion integration testing of large-scale aircraft models.  The tunnels are powered by a large compressor plant which allows the wind tunnels to run for extended periods of time.  The test unit is owned by the United States Air Force and operated by Aerospace Testing Alliance.

Arnold Air Force Base: Arnold Air Force Base (ICAO: KAYX, FAA LID: AYX) is a United States Air Force base located in Coffee and Franklin counties, Tennessee, adjacent to the city of Tullahoma.  It is named for General Henry "Hap" Arnold, the father of the U.S. Air Force.

Ent Air Force Base: The Ent Air Force Base was an Air Force base located in the Knob Hill neighborhood of Colorado Springs, Colorado.  A tent city, established in 1943 to build the base, was initially commanded by Major General Uzal Girard Ent (1900-1948) for whom the base is named.  The base was opened in 1951.  From 1957 to 1963, the base was the site of North American Aerospace Defense Command (NORAD), which moved to the Cheyenne Mountain Air Force Station.  The base became the Ent Annex to the Cheyenne Mountain facility in 1975.  The facility was closed in 1976 (becoming a Formerly Used Defense Sites).  The Ent Air Force Base site later became the location of the United States Olympic Training Center, which was completed July 1978.

Nevatim Airbase: Nevatim Israeli Air Force Base (Hebrew: בסיס נבטים‎ ‎ ) (IATA: VTM, ICAO: LLNV) , also Air Force Base 28, is an Israeli Air Force base located southeast of Be'er Sheva, near moshav Nevatim.  It was built as a rough runway in 1947 for the Sherut Avir, the air wing of the Haganah, and was named Malhata.  It was reopened in 1983 as a new modern airbase with two runways as the result of joint Israeli and US government funding as part of the IAF's redeployment out of its bases in the Sinai after it was returned to Egypt following the Camp David Accords.  Since 2003 the base has gradually received more squadrons of F-16s.  A third runway was built in the mid-2000s decade as part of a project to accommodate the transfer of military activities previously taking place at Ben Gurion Airport (Air Force Base 27) to Nevatim.

924th Fighter Group: The 924th Fighter Group is a group of the United States Air Force Reserve.  It assigned to Tenth Air Force and stationed at Davis-Monthan Air Force Base, Arizona as a Geographically Separated Unit (GSU) of the Air Force Reserve Command's 442d Fighter Wing at Whiteman Air Force Base, Missouri.  On 1 October 2012, the 924 FG was reassigned to the 944th Fighter Wing at Luke Air Force Base, Arizona.  The 924th flies the A-10 Thunderbolt II aircraft and is gained by Air Combat Command when mobilized.

Arnold Engineering Development Complex: Arnold Engineering Development Complex (AEDC), Arnold Engineering Development Center before July 2012, located at Arnold Air Force Base, Tennessee is a ground-based flight test facility operated by the Air Force Test Center.

Von Karman Gas Dynamics Facility: The von Karman Gas Dynamics Facility at Arnold Engineering Development Complex, Arnold Air Force Base, Tennessee, provide aerothermal ground test simulations of hypersonic flight over a wide range of velocities and pressure altitudes.  The facility consists of three Hypersonic wind tunnels: Tunnel A, B, and C.  The wind tunnels can be run for several hours at a time thanks to a 92,500 horsepower air compressor plant system.  The test unit is owned by the United States Air Force and operated by Aerospace Testing Alliance.

Double cantilever hangar: A Double cantilever hangar is a type of hangar that was constructed by the United States Air Force during the Cold War.  Large hangers were constructed at Castle Air Force Base, Loring Air Force Base, Carswell Air Force Base, and Travis Air Force Base, while smaller hangars were constructed at March Air Force Base, Edwards Air Force Base, Hanscom Air Force Base, and Homestead Air Force Base.

Henry H. Arnold: Henry Harley "Hap" Arnold (June 25, 1886 – January 15, 1950) was an American general officer holding the grades of General of the Army and General of the Air Force.  Arnold was an aviation pioneer, Chief of the Air Corps (1938–1941), Commanding General of the U.S. Army Air Forces, the only U.S. Air Force general to hold five-star rank, and the only officer to hold a five-star rank in two different U.S. military services.  Arnold was also the founder of Project RAND, which evolved into one of the world's largest non-profit global policy think tanks, the RAND Corporation, and one of the founders of Pan American World Airways.

Bakalar Air Force Base: Bakalar Air Force Base is a former U.S. Air Force base located 4.4 mi northeast of Columbus, Indiana.  During World War II, the base was known as Atterbury Air Field and Atterbury Army Air Base (named in memory of Brigadier General William Wallace Atterbury), but it was renamed Bakalar Air Force Base in 1954 in honor of First Lieutenant John Edmond Bakalar, USAAF.  Established in 1942, the airfield served as a training base for medium-range C-46 Commando and C-47 Skytrain troop carrier planes and glider pilots.  It also was used for training B-25 Mitchell and B-26 Marauder bomber crews.  Reactivated during the Cold War, it was used as an Air Force Reserve training base for troop carrier, tactical airlift, and special operations flying units.  The military base was closed in 1970.  The present-day facility operates as the Columbus, Indiana, municipal airport.
