Despite their difficulty seeing the runway at night and in marginal conditions, the Learjet 35A pilots canceled their instrument clearance and attempted an unauthorized to circle-to-land approach in El Cajon, California, U.S. The airplane, being repositioned following completion of a patient-transfer flight, stalled at low altitude and struck the ground, killing the two pilots and two flight nurses.
