A single misheard word led to disaster. Pacific Southwest Airlines Flight 182 collided with a Cessna 172 over San Diego, causing the deadliest U.S. air disaster of its time. Investigators uncover a tragic miscommunication and the fatal chain of errors that followed.
Pacific Southwest Airlines Flight 182 was a scheduled flight on September 25, 1978 by Pacific Southwest Airlines (PSA), from Sacramento to San Diego (SAN), with a stopover at Los Angeles (LAX).
The aircraft involved was a Boeing 727-214, collided mid-air with a private Cessna 172 (light aircraft; N7711G) over San Diego. It was Pacific Southwest Airlines' first fatal accident and it remains the deadliest air disaster in California history.
At the time, it was the deadliest air crash to occur in the United States and remained so until the crash of American Airlines Flight 191 in May 1979. Excluding intentional crashes, it currently stands as the seventh-deadliest to occur on American soil.
