This is the site of the crash of Pacific Southwest Airlines Flight 182 on September 25, 1978. I live a few blocks away. From Wiki:
Pacific Southwest Airlines (PSA) Flight 182 was a scheduled flight of Pacific Southwest Airlines from Sacramento to Los Angeles and San Diego. On September 25, 1978, the Boeing 727-214[a] serving the flight, registration N533PS, collided with a private Cessna 172 light aircraft, registration N7711G, over San Diego, California. It was Pacific Southwest Airlines' first fatal accident, and the deadliest air disaster in California history.
Both aircraft crashed into North Park, a San Diego neighborhood. PSA 182 struck just north of the intersection of Dwight and Nile streets, killing all 135 people aboard the aircraft and seven people on the ground in houses, including two children. The Cessna struck Polk Avenue between 32nd and Iowa streets, killing the two on board. Nine others on the ground were injured and twenty-two residences were destroyed or damaged by the impact and debris.
