Pulp Magazine Cover, August 1947

This issue of *Science & Mechanics* magazine contains UFO incident reports and analysis. The featured content includes "Incident 1/66," a detailed eyewitness account from St. Louis, Missouri, dated August 11, 1957, submitted by an aviation professional with twenty years' experience as a commercial pilot and aircraft mechanic. The observer describes seven to nine disc-shaped objects, black on one side and white/reflective on the other, traveling at approximately 1,000 mph in a vertical V-formation from south to north, observed by two softball teams and about twenty-five spectators including nine aircraft instructors. The objects alternated between black and light at two-second intervals. The magazine includes analytical commentary dismissing the sighting as a bright meteor, and an indexed catalog of UFO incidents organized by classification: astronomical phenomena (high probability), non-astronomical explanations including balloons and aircraft, and unidentified non-astronomical incidents. The index references over 240 documented sightings.
