Worst USA air crash at the time - San Diego, 1978.

[FrankPilot 124]

A Pacific Southwest Boeing 727 Airliner & a Cessna 172 collided mid-air near Lindbergh Field, San Diego in September 1978. The Boeing was on downwind to land & the Cessna was completing ILS practice. All on board the aircraft died, along with some on the ground. The aircraft were destroyed, along with houses on the ground. As is common, there was a chain of events leading to the disaster, but one stands out on its own. Come see how such a thing can happen. Hope you find this interesting. Cheers.
