Corona Municipal Airport , formerly L66, is three miles northwest of Downtown Corona, serving Riverside County, California, United States. The airport has a few businesses, such as a cafe, "Flying Academy" flight training center, and aircraft maintenance and repair. Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Corona Municipal Airport is AJO to the FAA and has no IATA code (Aljouf, Yemen has IATA code AJO). Facilities Corona Municipal Airport covers and has one asphalt runway, (7/25), 3,200 x 60 ft (975 x 18 m). In 2004 the airport had 68,000 aircraft operations, average 186 per day, all general aviation. 414 aircraft are based at the airport: 90% single engine, 6% multi-engine, 2% helicopter, 1% ultralight, and 1% jet. 24-hour fuel service is available all year (self serve). Incidents On March 19, 1998, a Cessna 152 clipped a private twin-engine plane, causing both planes to crash. The Cessna descended onto the corner roof of an apartment complex near the intersection of Chalgrove Drive and Border Avenue. No one was injured on the ground, but both pilots died. On January 21, 2008 two private planes collided in Corona, killing five people, including one on the ground. The collision occurred about a mile away from the Corona Municipal Airport above Serfas Club Drive. The crash wreckage left debris strewn along a commercial strip near the 91 Freeway. Eyewitnesses claimed to have seen an explosion in the air and two different bodies fall from the sky. The aircraft involved were both single-engine Cessnas, a two-seat Cessna 150 and a four-seat Cessna 172. Investigators from the National Transportation Safety Board, local Corona police detectives, and the Federal Aviation Administration began their probe the following day. As of January 23 a cause for the accident was yet to be determined. The crash began a debate about the safety of the Corona Municipal Airport, as it does not have an operating control tower. The city of Corona has had seven fatal aircraft accidents since 1998. On July 26, 2008 at approximately 13:47 local time, a baby blue and white 1947 Ercoupe stalled upon takeoff when turning crosswind and crashed into the forest on the southwest side of the airport. Eyewitnesses said that the two elderly pilots had minor injuries, with one of them bleeding from his right cheek where the yoke struck him upon impact. Both were alive, but
