Pilot in deadly California crash repeatedly warned to climb

THE AIR traffic controller repeated the warnings to the pilot more than a half-dozen times. Stop drifting, keep on course and a chilling, urgent plea: "Low altitude alert, climb immediately, climb the airplane."

Instead, the twin-engine plane plowed into a San Diego suburb, killing the pilot and a delivery driver on the ground and burning homes. Now, federal investigators must try to figure out what caused the crash that left a shocked and damaged neighborhood.
