A total of four private planes entered restricted airspace during President Barack Obama's visit to the Los Angeles area.
North American Aerospace Defense Command Lt. Cmdr. Bill Lewis says three of the planes that entered the restricted airspace Wednesday and Thursday were buzzed by F-16s and forced to leave the area and one pilot responded to radio commands to turn back.
Thursday morning, two small single-engine airplanes were escorted from restricted airspace by F-16s at 9 a.m. and 9:30 a.m. PDT.
On Wednesday, an F-16 fighter jet intercepted a Cessna 117 northwest of Los Angeles. That plane was forced to land at Camarillo.
A fourth plane responded to radio calls to turn around at 6:04 a.m. Thursday.
There have been similar incidents when Obama visited Los Angeles in the past.
