One person was believed to have been aboard a plane that crashed about 15 miles west of San Clemente Island shortly before noon Tuesday, Navy officials said.
The flier’s condition was not known.
The aircraft was an MU-2 Mitsubishi twin-engine turboprop, owned by Flight International in Carlsbad. The company is under contract with the Navy to provide target practice, but the plane was not operating in that capacity when it crashed, said Navy Cmdr. David Dillon, public information officer with the Naval Surface Force in Coronado.
The plane “was flying under (Navy) control, working with the Fleet Combat Training Center out of Point Loma,” Dillon said. “They train air traffic controllers; they don’t come under us.
The Navy was assisting in the search because there were Navy ships in the area when the plane went down, he said.
