From the Wikipedia article
American Airlines Flight 6-103 was a transcontinental flight from New York City to San Diego, with intermediate stops in Nashville, Dallas, El Paso, and Tucson. At 8:12 a.m. PST on the morning of March 3, 1946, the Douglas DC-3 operating the flight crashed into the slope of Thing Mountain, California, during its final leg from El Paso to San Diego. All 27 occupants on board were killed, including 3 crew, 22 adult passengers, and 2 infants.
The crash was at the time the deadliest American airliner accident.
The exact crash site was not known after the initial investigation until it was re-discovered in 2015.
Flight crew
The captain of the flight was Samuel Edward Stoner (age 30), of San Gabriel, California. He was employed by American Airlines in September 1939 and had 6,793 flight hours, 4,235 of which were in the Douglas DC-3.
The first officer was Emmett Edward Baker Jr. (age 25), of Brinkley, Arkansas. He was hired by American Airlines three months before the accident and had 3,300 flight hours, 1,000 of which were obtained during his time in the Navy.
There was one stewardess aboard the flight: Maxime Catherine Rickard (age 23). All members of the flight crew were properly certified and qualified for the flight.
Accident
American Airlines Flight 6-103 departed New York City at 9:02 a.m. on March 2, 1946. Crew changes were made in Nashville and El Paso, and the flight from New York to El Paso was uneventful.
The flight left El Paso at 3:25 a.m. on the morning of March 3, 1946. After arriving in Tucson at 5:37 a.m., it departed for San Diego at 5:59 a.m. The pilots gave routine position reports to air traffic control over Casa Grande, Gila Bend, and Yuma, Arizona. At 7:53 a.m., the flight reported its position over El Centro, California, at an altitude of 8,000 feet.
Air traffic control in Los Angeles delivered a clearance of 8000 feet cruising altitude for the flight to the American Airlines radio station in San Diego. The station then attempted to contact Flight 6–103, but all further attempts were unsuccessful.
Wreckage of Flight 6-103 was discovered at 1:05 p.m. the same day by a naval aircraft on the eastern slope of Thing Mountain, at an altitude of 4,870 feet, approximately 50 miles east of San Diego. All 27 passengers and crew were killed in the crash.
Investigation and cause
Probable cause
According to the Civil Aeronautics Board which investigated the accident, "the probable cause was the action of the pilot in descending or permitting a descent to be made, into instrument conditions to an altitude below that required to maintain clearance over Thing Mountain. The reason for the descent has not been determined."
