Circle over Cayo Guillermo (Cuba), Cuba
A witness account on file, unevaluated. Most of the archive rests here, and honestly so.
The report, as filed
While walking on a very dark and extremely quiet night, my 3 companions and me witnessed a round orange object approach from the west. It was travelling in a straight line, parallel to the ground. Elevation was about 15000 feet. Speed was about 1000 miles per hour. At first, the colour was a dim orange, but became very bright as it passed overhead. It seemed as though it was burning. The arc of view was about 90 degrees. The relative size was about the size of a pencil eraser held at arm's length when it was overhead. What was so memorable was that at no time did it make sound. About 5 minutes later, I alone witnessed a similar object flying in the same direction, but much higher. About the size of a star.
