On January 29, 1987, Alaska Airlines Flight 53 reported an unidentified target on their weather radar while flying at 35,000 feet near McGrath, Alaska. The target moved rapidly and was not visually confirmed by the crew. FAA and USAF investigations found no other aircraft in the area.

…urred on November 17, 1986, and involved two smaller lights and a massive object described as being twice the size of an aircraft carrier. The FAA and military radar initially detected the object, but later investigations attributed the radar signals to electronic clutter.

…ragmented and corrupted report related to unidentified aerial phenomena (UAP) sightings and investigations, primarily from the 1950s. It includes references to radar detections, military communications, and possible sightings of flying saucers, but the text is largely unintelligible due to formatting issues.
