Brad Sparks is a researcher who compiled a catalogue of Project Blue Book unknowns. Case after case passes through his list. There is the Fukuoka F-61 intercept of 1948, filed as Case 123. The Guam F-86D chase of 1956 became Case 1217. In 2000 he sat down with Capt. Willis T. Sperry, then 98, for the Sign Oral History Project. He also challenged official explanations. He argued that the geometry of the 1954 BOAC sighting ruled out a mirage. And he called the 1957 RB-47 encounter the first conclusive scientific proof for the existence of UFOs.
