On the morning of June 14, 1985, Aircraft Pilot (Trainee) Lester L. Haynie had been working with ground units 12 miles west of Yuma, Arizona. Having apprehended five aliens at Dunes Siding, Pilot Haynie radioed the ground units that he was flying to another siding. There were no witnesses to the crash which occurred at 7:51 a.m., and reported at 8:18 a.m. by a Southern Pacific Railroad engineer. The Border Patrol plane was upside down under San Diego Power and Light cables in Imperial County, California, 100 yards north of the Southern Pacific Railroad tracks near Dunes Siding, two miles west of Sidewinder Road. An investigation determined that Pilot Haynie had failed to gain altitude to clear the power lines.
