Project 10073 Record — Minneapolis, Minnesota, 18 April 1967

This document is a Project 10073 record detailing a UFO sighting that occurred on April 18, 1967, in the vicinity of the Minneapolis-St. Paul International Airport. The report describes an observation lasting approximately 40 minutes, involving between one and three round, orange-glowing objects, each estimated to be the size of a breadbox. Witnesses reported that the objects occasionally trailed a stream of flames or sparks and exhibited movement that was slower than an airplane, with abrupt changes in direction. The objects were observed between 2010 and 2050 local time. The report notes that the control tower was unable to confirm the sighting visually or with binoculars. Weather conditions were reported as clear with good visibility. The investigating officer, Captain John M. [illegible] of the 934th Troop Carrier Group, conducted an investigation involving the U.S. Weather Bureau and local air traffic control. Based on these inquiries, the officer concluded that the phenomena were likely hot air balloons with candles, released by pranksters.
