One mile north of Bonny Spring Ranch, on U.S. Highway 91, two civilians in a car observed in the rear-view mirror a low-flying object that overtook their car, followed by a rush of cold air. It stopped, circled the vehicle, flew off and was lost to sight behind the mountains, where it may have landed. In the course of an exceptionally complete investigation by military authorities, however, no evidence of a landing was discovered.

One saucer was observed by two witnesses on a highway.
