Los Angeles World Airports (LAWA) owns 17,000 acres east of Plant 42 that was acquired for an airport. The city of Los Angeles bought the land in the 1960s when it planned to build an airport in Palmdale, but the airport was never built. In March 2001 Los Angeles County hired Tri-Star Marketing to prepare the presentations needed to bring air-passenger service back to Palmdale Regional Airport. However, the regional transportation plans formulated by the Southern California Association of Governments focus on having airports in Burbank, Ontario, Irvine and El Toro to handle the excess air-passenger service for the Southern California region.
