Little Rock National Airport (IATA: LIT, ICAO: KLIT, FAA LID: LIT), officially designated Adams Field, is located 2 miles (3 km) east of the central business district (CBD) of Little Rock, a city in Pulaski County, Arkansas, USA. It is Arkansas' largest commercial service airport, serving more than 2.5 million passengers in 2005. The airport attracts passengers from a large part of Arkansas as well as a number of surrounding states.
Although the airport does not have direct international passenger flights, there are more than 150 flight arrivals and departures at Little Rock each day, with non-stop jet service to 18 national/international gateway cities.
The regional jet made its first appearance at Little Rock National in 1997, with three daily flights by Delta Connection carrier, Comair, to Cincinnati. Comair has now been joined by other Delta Connection carriers as well as American Eagle, Continental Express, Frontier JetExpress, Northwest Airlink, United Express, and US Airways Express in operating the regional jet at Little Rock.
The Delta region is bisected by an unusual geological formation known as Crowley's Ridge. A narrow band of rolling hills, Crowley's Ridge rises from 250 to 500 feet (150 m) above the surrounding alluvial plain and underlies many of the major towns of eastern Arkansas.
Northwest Arkansas is part of the Ozark Plateau including the Boston Mountains, to the south are the Ouachita Mountains and these regions are divided by the Arkansas River; the southern and eastern parts of Arkansas are called the Lowlands. All of these mountains ranges are part of the U.S. Interior Highlands region, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains. The highest point in the state is Mount Magazine in the Ozark Mountains; it rises to 2,753 feet (839 m) above sea level.
Arkansas is home to many caves, such as Blanchard Springs Caverns. It is also the first U.S. state in which diamonds were found (near Murfreesboro). Arkansas has the only operating diamond mine in the United States.
The Federal Aviation Administration (FAA) is an agency of the United States Department of Transportation with authority to regulate and oversee all aspects of civil aviation in the U.S. The Federal Aviation Act of 1958 created the group under the name "Federal Aviation Agency", and adopted its current name in 1967 when it became a part of the United States Department of Transportation.
