Hill Air Force Base

Hill Air Force Base (IATA: HIF, ICAO: KHIF, FAA LID: HIF) is a major U.S. Air Force base located in northern Utah, just south of the city of Ogden, and near the towns of Clearfield, Riverdale, Roy, Sunset, and Layton. It is about 30 miles (48 km) north of Salt Lake City. The base was named in honor of Major Ployer Peter Hill of the U.S. Army Air Corps, who died test-flying a prototype of the B-17 Flying Fortress bomber. In this decade Hill AFB is still the sixth-largest employer in the state of Utah, and the third-largest one excluding the State Government and Higher Education employers. Hill AFB is the home of the Air Force Materiel Command's (AFMC) Ogden Air Logistics Complex which is the worldwide manager for a wide range of aircraft, engines, missiles, software, avionics, and accessories components. The commander of the Air Logistics Complex is Brigadier General H. Brent Baker Sr. The Ogden Air Logistics Complex is part of the Air Force Sustainment Center.

The host unit at Hill AFB is the Air Force Material Command's 75th Air Base Wing (75 ABW), which provides services and support for the Ogden Air Logistics Complex and its subordinate organizations. The Wing and Installation Commander of Hill Air Force Base is Colonel Ronald Jolly. Additional tenant units at Hill AFB include operational fighter wings of the Air Combat Command (ACC) and the Air Force Reserve Command (AFRC).

Force play

In baseball, a force is a situation when a baserunner is compelled (or forced) to vacate his time-of-pitch base—and thus try to advance to the next base—because the batter became a runner. A runner at first base is always forced to attempt to advance to second base when the batter becomes a runner. Runners at second or third base are forced only when all bases preceding their time-of-pitch base are occupied by other baserunners and the batter becomes a runner.

A forced runner's force base is the next base beyond his time-of-pitch base. Any attempt by fielders to put a forced runner out is called a force play. Think of forced runners as bumper cars. If with a runner on first, the batter hits a ground ball, the batter must run to first, and since two runners are not allowed to stay on one base at one time, the runner who was on first to begin with is now bumper-carred by the advancing batter over to second. If there already was a runner on second as well, that runner is now bumper-carred over to third, and so on. If a runner is bumper-carred over to the next base by the advancing batter or by another runner who was bumper-carred by the advancing batter, then that runner is considered to have been forced to advance to the next base. If, however, with a runner on third, for example, the batter hits a ground ball, the batter must run to first, but the runner on third, not having been bumper-carred by the batter, is not forced to advance and can stay where he is if he elects to.

Military airbase

An military airbase (sometimes referred to as a military airfield, military airport, air force station, air force base or short airbase) is an aerodrome used by a military force for the operation of military aircraft.

Airbase facilities

An airbase typically has some facilities similar to a civilian airport—for example air traffic control and firefighting. Some military aerodromes have passenger facilities; for example RAF Brize Norton in England has a terminal used by passengers for the Royal Air Force's flights by TriStar to the Falkland Islands. A number of military airbases also have a civil enclave for commercial passenger flights, e.g. Beijing Nanyuan Airport (China), Ibaraki Airport (Japan), Burlington International Airport (USA).

Some airbases have revetments, hardened aircraft shelters, or even underground hangars, to protect aircraft from enemy attack. Combat aircraft require storage of aircraft ordnance. An airbase may be defended by anti-aircraft weapons and force protection troops.
