Sioux Gateway Airport

The construction of Sioux City Army Air Base began in March 1942, about three months after the Japanese attack on Pearl Harbor. Opened on July 5, 1942, it became a major training center during World War II for crewmen of B-24 Liberators and B-17 Flying Fortresses. With the end of World War II, the former training base switched to becoming a processing center to discharge personnel out of the service and back into civilian life. Sioux City Army Air Base closed in December 1945, but in September 1946, the airfield was opened by the Air Force Reserve. Sioux City Air Base was one of the first Air Force Reserve bases established after the war, and in December 1946, the 185th Iowa Air National Guard unit was established at Sioux City. Assigned to the new Air Defense Command (ADC) upon reactivation, the 140th Army Air Force Base Unit was activated as its host organization. The mission of the 140th AAFBU was to offer flight and ground training to all commissioned and enlisted members of the Air Force Reserve residing in Iowa, Minnesota, Nebraska, South Dakota and Wyoming. By the mid-1960s, ADC was reducing its forces, and on April 1, 1966, the 31st AD was reassigned and the airport was turned over to the Air Force Reserve and Iowa Air National Guard for limited military use. SUX controversy The airport designator "SUX" has been contentious, due to the name sounding identical to the slang word "sucks". Sioux City Mayor Craig Berenstein in 2002 described SUX as an "embarrassment" to the city. After petitioning the FAA for a changed airport identifier in 1998 and 2002, authorities found the alternatives offered - GWU, GYO, GYT, SGV, and GAY - to be unappealing, and elected to stay with SUX. Airport growth For several years the only airline service was from Northwest Airlines, commuter service on Northwest Airlink to Minneapolis–Saint Paul International Airport. In October 2007, Frontier Airlines began service with two daily flights between its Denver hub and Sioux City. The new service from Frontier quickly expanded to three daily non-stop flights to Denver and helped passenger traffic increase by over 150%. In July 2011, Delta Air Lines (who merged with Northwest in 2009) told the United States Department of Transportation that a weak economy and lower seat demand would force the company to reduce flights to several smaller communities including Sioux City unless it received assistance from the federal government. Delta said planes left Sioux Gateway with an average of only 51.4% of their seats full, so given that the company planned to remove turboprop planes and some of its 50-seat jets from service by the end of 2011 it wasn't economically viable for Delta to continue service. Delta made its final flights into Sioux Gateway in April 2012. American ended service to Sioux City on April 5, 2021. == Facilities and aircraft ==

Sioux Gateway Airport covers 2,460 acres (996 ha) at an elevation of 1,098 feet (335 m) above mean sea level. It has two runways: 13/31 is 9,002 by 150 feet (2,744 x 46 m) concrete and 18/36 is 6,401 by 150 feet (1,951 x 46 m) asphalt. The City of Sioux City received federal and state funds that picked up 78 percent of the $6.2 million cost to renovate the terminal building. The city received a Federal Aviation Administration grant for the new passenger loading bridge, plus $3.97 million in federal stimulus funds and a state Airport Vertical Infrastructure grant. The city's share was $1.4 million, which was about twice as much as originally estimated caused construction problems due to termite and drainage damage. In the year ending December 31, 2021, the airport had 19,509 aircraft operations: an average of 53 per day: 51% general aviation, 25% military, 14% air taxi, and 9% airline. At that time, there were 66 aircraft based at SUX: 41 single-engine, 3 multi-engine, 11 jet, 2 helicopters, and 9 military. ==Airline and destinations==

Passenger ==Accidents and incidents==

• On January 31, 1944, a United States Army Air Forces Douglas C-39 en route to Saint Joseph, Missouri, caught fire shortly after takeoff, crashed and burned. All three crew members died. • On March 2, 1951, a Mid-Continent Airlines Douglas DC-3 crashed 500 feet short of runway 17 while attempting to land in a snowstorm. The probable cause of the crash was a stall at low altitude while turning to line up on the runway. 16 of 25 occupants were killed in the crash. • On December 27, 1968, an airplane operating as Ozark Air Lines Flight 982 crashed while taking off from runway 35 at Sioux Gateway Airport en route to Chicago. The plane was inadequately deiced, causing it to have no control after takeoff. The plane rolled violently 90 degrees to the right and then overcorrected to a mild left bank, causing the left wing to strike the ground. The plane came to rest in a flat position 1181 feet past the runway end. There were injuries but no fatalities. • On July 19, 1989, United Airlines Flight 232, en route from Denver-Stapleton to Philadelphia via Chicago-O'Hare, crashed at Sioux Gateway Airport while attempting an emergency landing. 111 passengers and 1 crew member were killed, while 174 passengers and 10 crew members survived. The accident was one of the most famous aviation disasters in American history, due to several factors: the nature of the incident (deemed as "unsurvivable", especially as it compared in similarity to the earlier Japan Air Lines Flight 123 crash), the skill of the crew in saving many of the occupants, the survival of so many occupants despite the circumstances and because of the media exposure. The actual footage of the crash was used three years later for the making of the Charlton Heston and James Coburn made-for-TV movie Crash Landing: The Rescue of Flight 232 (1992; also known as A Thousand Heroes) about the beginnings (and ultimate test) of the Woodbury County Disaster Services program. == See also ==
