Good to see you mate, well said and think that aspect is deserving of a thread in itself - looks like the 'residue' could probably be more like 20%. Dr Hynek states that about 20 percent of Bluebook cases could not be explained (great interview). Researcher Kevin Randle on numbers: Researcher George Fawcett on numbers: When it comes to Battelle Memorial Institute's BB14 actual unknown 20% unexplained rate (21.5% out of 3201 cases) then Ruppelt also describes the classification status below. • USAF attempts to mislead the public on numbers. Ruppelt also discusses radar UFO tracking and 25% unexplained rate in this article. Also, not to go on about it but there's a 1949 Government document below sent to the Director of Intelligence entitled which it states that only 20% of UFO incidents have been explained. Won't even bother with the Condon report unexplained rate (30% possibly 50%) but always seem to hear the 5% figure being bandied about by debunkers on cheesy TV shows when think it's fair to say the general consensus from official government UFO studies is far more like a conservative 20%. Cheers.
