At approximately 2120 Central time, a light, with a brilliance slightly greater than a star appeared from the West travelling in an easterly direction at a high rate of speed. It first appeared slightly above the horizon of a clear moon-light night. There was no audible sound. It appeared to be at great height although it was impossible to determine the altitude. It traveled a zig-zag course with frequent bursts of speed similar to a water but salt spurts and stops across the surface of water. Directly overhead, it changed course 90° into the south. After 5 minutes it turned southwest and was lost in the brilliancy of the moon. At 2145 Central it was not longer possible to observe it. A cell was placed to Nasswell Fld operations concerning the chenogene and inquiry was made if any experimental aircraft were scheduled for a flight in the vicinity but the reply was negative. No plausible explanation was offered for the unusual action of this source of light which acted contrary to any common aerodynamical law. Two of the above noted observers were rated pilots and the other two,air intelligence officers.
