Fighter jets intercepted two aircraft that wandered into the restricted zone during President Obama's Los Angeles visit.
Air Force Master Sgt. Chuck Marsh, a spokesman for North American Aerospace Defense Command, says a small private plane and a private helicopter were spotted in the no-fly zone around 6:30 p.m. Wednesday and authorities couldn't immediately make contact with the pilots.
California Air National Guard F-15s eventually escorted the aircraft out of the restricted area.
One landed at McClellan-Palomar Airport in Carlsbad and the other at Agua Dulce Airport.
Authorities say no planes violated restrictions during the president's visits Thursday in Los Angeles, Beverly Hills and San Diego. He's now in Northern California.
