In 1975 while having a cookout for the residents of out apartment complex I witnessed 5 lighs in a V- shaped flying pattern.They did not blink or change colors. They moved from the south to the north at a very slow speed. I kept listening to for the sound jet but there was absoulutely no sound. As the objects came over head we could see the stars between the objects. There were several student employees in engineering school at Red River Army depot who witnessed this. They swore they would never repeat the sighting for fear of losing their jobs. I you were to draw a line right down Hwy 8 south to north that was approximately the flight direction. Just a few hundred feet from RRAD property. These objects wereflying at approximately 18,000 to 25,000 feet.
