Visual sightings and radar tracking of UFOs in the vicinity of military installations have been reported since the beginning of the modern era. The number and nature of most of these events has been kept from the public by military security, but on occasion information has been released, although its significance is usually played down.

From late October through the middle of November 1975, high-security bases along the U.S.-Canada border were the scene of intrusions of what were euphemistically called "mystery helicopters," despite their unhelicopter-like appearance and behavior.

The most complete recounting of the events from anyone in the U.S. or Canadian Governments is from the Commander-in-Charge of the North American Aerospace Defense Command (NORAD), on November 11, 1975:

"Part I. Since 28 Oct. '75, numerous reports of suspicious objects have been received at the NORAD CU. Reliable military personnel at Loring AFB, Maine, Wurtsmith AFB, Michigan, Malmstrom AFB, Montana, Minot AFB, North Dakota, and Canadian Forces Station Falconbridge, Ontario, Canada, have visually sighted suspicious objects.

"Part II. Objects at Loring and Wurtsmith were characterized to be helicopters. Missile Site Personnel, Security Alert Teams, and Air Defense Personnel at Malmstrom AFB, Montana report an object which sounded like a jet aircraft. FAA advised there were no jet aircraft in the vicinity. Malmstrom search and height finder radars carried the object between 9,500 ft. [2,900 m.] and 15,600 ft. [4,850 m.] at a speed of seven knots [9 mph or 14 km./hr.]. There was intermittent radar contact with the object from 080753Z through 0900Z November 1975. F-106's scrambled from Malmstrom could not make contact due to darkness and low altitude. Site personnel reported the object as low as 200 ft. [60 m.] and said that as the interceptors approached, the lights went out. After the interceptors had passed, the lights came on again, one hour after the F-106's returned to base. Missile site personnel reported the object increased to a high speed, raised [sic] in altitude and could not be discerned from the stars.

"Part III. Minot AFB on 10 Nov. reported that the site was buzzed by a bright object the size of a car at an altitude of 1,000 to 2,000 ft. [300 to 600 m.]. There was no noise emitted by the vehicle.

"Part IV. This morning, 11 Nov. '75 CFS Falconbridge reported search and height finding radar paints on an object 25 to 30 nautical miles [30 to 35 statute miles or 48 to 56 km.] south of the site ranging in altitude from 26,000 ft. to 72,000 ft. [6,500 m. to 18,000 m.]. The site commander and other personnel say the object appeared as a bright star but much closer. With binoculars, the object appeared as a 100 ft. diameter sphere and appeared to have craters around the outside.

"Part V. Be assured that this command is doing everything possible to identify and provide solid factual information on these sightings. I have also expressed my concern to SAFOI [Secretary of the Air Force, Office of Information] that we come up soonest with a proposed answer to queries from the press to prevent over reaction by the public to reports by the media that may be blown out of proportion. To date, efforts by Air (National) Guard helicopters, SAC helicopters and NORAD F-106s have failed to produce positive ID [identification]."

The most important fact omitted from the NORAD report was that many of the sightings were of objects over or near areas used for the storage of nuclear weapons. This fact is clearly established by other declassified documents which mention that, "in the interest of nuclear weapons security the action addressees will assume Security Option III during hours of darkness until further notice." A SAC message on the subject of "Defense Against Helicopter Assault," captures the alert mood:

"Several recent sightings of unidentified aircraft/helicopters flying/hovering over Priority A restricted areas during the hours of darkness have prompted the implementation of security Option 3 at our northern tier bases. Since 27 Oct. 75, sightings have occurred at Loring AFB, Wurtsmith AFB, and most recently, at Malmstrom AFB. All attempts to identify these aircraft have met with negative results."75

With the exception of the object reported form CFS Falconbridge, only limited descriptions were given of the appearance of the UFOs. From a variety of military sources come these descriptions:

"October 28, Loring AFB, Maine. Unknown craft with a white flashing light and an amber or orange light. Red and orange object, about four car-lengths long. Moving in jerky motions, stopped and hovered. The object looked like all the colors were blended together; the object was solid.

"October 30, Wurtsmith AFB, Michigan. One light pointing downward, and two red lights near the rear. Hovered and moved up and down in an erratic manner. A KC-135 aerial tanker crew established visual and radar contact with UFO: 'Each time we attempted to close on the object, it would speed away from us. Finally, we turned back in the direction of the UFO and it

really took off... I know this might sound crazy, but I would estimate that the UFO sped away from us doing approximately 1,000 knots [1,150 mph or 1,800 km./hr.].'

"November 7, Malmstrom AFB, Montana. A Sabotage Alert Team described seeing a brightly glowing orange, football field-sized disc that illuminated the Minuteman ICBM missile site. As F-106 jet interceptors approached, the UFO took off straight up, NORAD radar tracking it to an altitude of 200,000 feet [38 miles or 60 km.]. An object... emitted a light which illuminated the site driveway. The orange-gold object overhead also has small lights on it.

"November 8, Malmstrom AFB. Radar showed up to 7 objects at 9,500 to 15,000 feet [2,900 m. to 4,700 m.]. Ground witnesses reported lights and the sound of jet engines, but radar showed objects flying at only 7 kts. [8 mph or 13 km./hr.].

"November 10, Minot AFB, North Dakota. A bright, noiseless object about the size of a car buzzed the base at 1,000-2,000 feet [300-600 m.]."
