The following were documents obtained from the Office of the Assistant Secretary of Defense, Freedom of Information and Security Review Office. It was released to The Black Vault in September of 1997, through FOIA Case 97-F-1677 (though it had been released prior to other researchers for some time).
The Rendlesham Forest incident was a series of reported sightings of unexplained lights near Rendlesham Forest in Suffolk, England in late December of 1980 which became linked with claims of UFO landings. The events occurred just outside RAF Woodbridge, which was used at the time by the United States Air Force (USAF). USAF personnel, including deputy base commander Lieutenant Colonel Charles I. Halt, claimed to see things they described as a UFO sighting. (Wikipedia)
Below, you will find the infamous “Halt Memo.” This memo describes in a single page memorandum, the events that occurred.
There are many facets to this story, and witnesses who have come forward. However, this page was setup to archive the memo specifically for research purposes.
DEPARTMENT OF THE AIR FORCE HEADQUARTERS COMBAT SUPPORT GROUP (USAFC) APO NEW YORK REPLY TO: 13 JAN 81 CD ATIN OF. SUBJECT: Unexplained Lights TO: RAF/CC 1. Early in the morning of 27 Dec 80 (approximately 0300L),two USAF security police patrolmen saw unusual lights outside the back gate at RAF Woodbridge. Thinking an aircraft might have crashed or been force down, they call for permission to go outside the gate to investigate. The on-duty flight chief responded and allowed three patrolmen to pro- ceed on foot. The individuals reported seeing a strange glowing object in the forest. The object was described as being metalic in appearance and triangular in shape, approximately two to three meters across the base and approximately two meters high. It illuminated the entire fo- rest with a white light. The object itself had a pulsing red light on top and a bank(s) of blue lights underneath. The object was hovering or on legs. As the patrolmen approached the object, it maneuvered th- rough the trees and disappeared. At this time the animals on a nearby farm went into a frenzy. The object was briefly sighted approximately an hour later near the back gate. 2. The next day, three depressions 1 1/2" deep and 7" in diameter were found where the object had been sighted on the ground. The foll- owing night (29 Dec 80) the area was checked for radiation. Beta/Gamma readings of 0.1 milliroentgens were recorded with peak reading in the three depressions and near the center of the triangle formed by the depressions. A nearby tree had moderate (.05-.07)readings on the side of the tree toward the depressions. 3. Later in the night a red sun-like light was seen through the tree . It moved about and pulsed. At one point it appeared to throw off glowing particles and then broke into five separate white objects and then disappeared. Immediately thereafter, three star-like objects were noticed in the sky. Two objects to the north and one to the south , all of which were about 10 degrees off the horizon. The objects moved rapidly in sharp angular movements and displayed red, green and blue lights. The objects to the north appeared to be elliptical thro- ugh an 8-12 power lens. They then turned to full circles. The objects to the north remained in the sky for an hour or more. The object to the south was visible for two or three hours and beamed down a stream of light from time to time. Numerous individuals, including the unde- rsigned, witnessed the activities in paragraphs 2 and 3. CHARLES I. HALT, Lt Col, USAF Deputy Base Commander
