This gripping read is based on an original book by .Edward J. Ruppelt who was the head of the United States Air Force UFO research - Project Blue Book - from 1951 until 1953. He of course had a unique insight into what went on within that project at that time. He died at the age of just 37 in 1960. Newly edited, and with some new illustrations added, this is a must have book for the person interested in Unidentified Flying Objects.
