The filming location was
Indian Dunes, a movie ranch in the
Valencia neighborhood of
Santa Clarita, California, that was used throughout the 1980s in films and television shows. The location was within the
studio zone, its wide-open area permitted more pyrotechnic effects, and it was possible to shoot night scenes without city lights being visible in the background. Indian Dunes' also featured a wide topography of green hills, dry desert, dense woods, and jungle-like riverbeds along the
Santa Clara River which made it suitable to double for locations around the world, including Afghanistan, Myanmar, Brazil, and Vietnam. The night scene called for Morrow's character to carry the two children out of a deserted village and across a shallow river while being pursued by American soldiers in a hovering helicopter. The helicopter was piloted by Vietnam War veteran Dorcey Wingo. In an aircraft accident report, the
National Transportation Safety Board subsequently wrote: At the trial, the defense claimed that the explosions were detonated at the wrong time. Randall Robinson was an assistant cameraman on board the helicopter who testified that
production manager Dan Allingham told Wingo, "That's too much. Let's get out of here" when the explosions were detonated, but Landis shouted over the radio: "Get lower... lower!" Robinson said that Wingo tried to leave the area, but that "we lost our control and regained it and then I could feel something let go and we began spinning around in circles." Lydecker acknowledged that Landis might have been joking when he made the remark, but added, "I learned not to take anything the man said as a joke. It was his attitude. He didn't have time for suggestions from anybody." ==Investigation==
