Air Force One is shown landing in Orange County, but the only commercial airport in Orange County, California is John Wayne Airport, whose runways can not accommodate Boeing 747s (such as Air Force One). Presidents visiting Orange County normally land at Los Angeles International Airport (LAX), the nearest airport capable of handling a 747.
Some guy tells the president that a fuel truck is parked under the LEFT wing of AF1. But earlier there's a scene showing the truck under the RIGHT wing.
