UFO: A Deadly Concealment - The Official Cover Up? by Derek Sheffield
In 1990, four separate NATO radar stations in Germany and Belgium tracked a 1000mph (1600kph) triangular-shaped flying object across western Europe and into British air space. Despite official documentation the governments concerned denied the facts and concealed the evidence. This book presents the facts about the incident which has now been officially recorded in Belgian and UK government records. The author's claims have been endorsed by UK Admiral of the Fleet, Lord Hill Norton.
