Multicolored UFO seen in Michigan in 1966

Summary

In April 1966, two observers in Michigan reported a multicolored UFO displaying unusual behavior. First, they saw a round object with red, green, and blue colors moving westward. Later, the object began pulsating like a heartbeat, growing larger and following their truck before disappearing. Later, a bright white object passed over them, traveling south toward Ovid and then returning bigger than before. Observers described details like a blue trail with sparks and no noise, raising doubts about its nature. Despite multiple sightings, authorities concluded there was insufficient data for a definitive evaluation.
