Insufficient Data

Summary

On December 13, 1960, three pilots observed four unidentified flying objects at different times over the Atlantic Ocean west to north of their position. The pilots were conducting visual flight training exercises when they spotted the objects flying between 15,000 and 40,000 feet. One pilot described an object with a cone or smoke trail observed against a bright star background. The objects moved at speeds ranging from hypersonic to Mach ten with estimated elevation of 14 to 15 degrees above the horizon. No radar contacts were made by local ground control intercept stations. The Air Force evaluation is unknown.

10. BRIEF SUMMARY OF SIGHTING
3 pilots observed first UFO and one each observed remaining contacts. Observed object while flying at from 1500-40,000 ft. Trail of objects varied from whitish to reddish and reportedly no longer than normal meteor. One pilot at forty thousand feet described object a white star background. No supersonic radar contacts made by local GCI station during period.

11. COMMENTS
During this period there are several meteor showers taking place. The brightest of those showers, "The Geminids," were probably responsible for the observations. Descriptions of objects tend substantiate fact that objects were probably meteors. Actually one witness inferred that they were meteors by describing them as "brighter than normal meteors."
