Pacific Southwest Airlines Flight 1771

Pacific Southwest Airlines Flight 1771 was a scheduled flight along the West Coast of the United States, from Los Angeles, California, to San Francisco. On 7 December 1987, the British Aerospace 146-200A, registration N350PS, crashed in San Luis Obispo County near Cayucos, after being hijacked by a passenger.

All 43 passengers and crew aboard the plane died, five of whom, including the two pilots, were presumably shot dead before the plane crashed. The perpetrator, David Burke, was a disgruntled former employee of USAir, the parent company of Pacific Southwest Airlines. The crash was the second worst mass murder in modern Californian history, after the similar crash of Pacific Air Lines Flight 773 in 1964.
