UFO seen in Minnesota in 1966

Summary

In August 1966, a family in Minnesota observed an unidentified flying object that appeared to have long, straight wings, similar to a large aircraft. The object was so large that its wingspan covered the full moon and had red, green, and white flashing lights. Although the fuselage was not visible, the observers noted that it remained stationary in the sky while they drove underneath it for about 15 minutes. The report, sent by Project Blue Book, requested more details from the witnesses for a more accurate evaluation, but no physical evidence or photographs were found. The description of the object and its behavior generated curiosity and confusion among the observers.
