USN Naval Research Lab, NRL, rocket scientist/engineer Dr. Carl J. Zohn, Admin Asst., Rocket Sonde Section, White Sands Proving Ground, WSPG, NRL scientist Curtis C. Rockwood and his wife, and WSPG technician John R. Kauke, were driving in a car from Las Cruces to WSPG headed northeast when they saw to their right front, east, a rotating silvery or shiny disk or sphere with no appendages, wings, tail, propellers, reflecting sunlight, pulsating, crossing the sky at high speed heading north at about 8,000' to 10,000' which suddenly disappeared in mid air in a clear cloudless sky.
Kauke had stopped the car and briefly saw a short vapor trail at one point not reported by the others. Zohn on the passenger side rolled the window for an unobstructed view.
