A Cessna 414 crashed into the Pacific Ocean off San Diego, killing all six aboard shortly after takeoff. The pilot issued a mayday call, citing difficulty maintaining heading and altitude. The plane failed to reach a nearby naval base for an emergency landing.

The aircraft reportedly had issues maintaining altitude and heading. The Coast Guard attempted rescue missions but could find no survivors.
