Project 10073 Record Card — Silver Bay & Gilbert, Minnesota, 22 Feb 61

This document is a Project 10073 record card and associated teletype communications regarding a sighting on February 22, 1961, in Minnesota. Observers in Silver Bay and Gilbert reported a brilliant, round, tapered, cone-shaped object exhibiting vivid red, green, and blue colors. The object was described as trailing fire and sparks, moving at extremely high speeds—estimated by one witness as six or seven times faster than an F-106 aircraft—and producing a sound described as a sonic boom. One witness, a policeman named Garfield Gulbranson, reported that the object broke into three or four pieces before disappearing behind trees. A separate, potentially related sighting occurred on the same day at Lac La Croix, where three men, including a pilot and a deputy sheriff, observed five objects in formation heading from south to north. These objects were described as round and dome-shaped with greenish-hued tails, traveling at a tremendous rate of speed. The official conclusion for the primary sighting was that the object was a rare daylight meteor of sufficient size to be heard upon explosion. The document includes meteorological data for the area, which was reported as clear with unlimited visibility. The report was eventually declassified in May 1969.
