OAKLAND (AP) — Federal authorities said fighter jets were scrambled to intercept a small plane that had lost contact with traffic controllers over California Sunday.

Federal Aviation Administration spokesman Mike Fergus said the Cessna 172 was flying from Santa Monica to Oakland on Sunday morning when it lost radio contact with air traffic controllers somewhere near Ventura.
