I think the following on Dr Hynek from a recent report of my UFO Research site may form a good review of the man's contribution.
The UFO Hunters team in the States have contacted NWUR Founder, Pat Regan, expressing interest in the local Orange Ball phenomena.
Dave Pavoni producer stated that the team call the latest sightings "ORBLs" - known as Orange Balls of Light - "Hynek investigated them and they are a known UFO term" added Mr Pavoni. Who was Hynek?
Dr J. Allen Hynek, was a Astronomy professor at Ohio State University, who went on to become Associate Director of the Smithsonian Astrophysical Observatory in 1956), and chairman of the Astronomy Department at Northwestern University during 1960). Hynek is best remembered, though, for his contribution to research into unidentified flying objects. This commenced in 1949 when he was invited by the US Air Force to become the astronomical consultant to Project Grudge, based at nearby Wright Field (later Wright-Patterson AFB), in Dayton. He continued in this position with the successive and much longer Project Blue Book, gradually shifting over the years from a position of extreme scepticism to one in which he believed that UFOs represent "an aspect or domain of the natural world not yet explored by science."
In 1973, four years after the termination of Project Blue Book, Dr Hynek founded the Centre for UFO Studies (CUFOS), based in Chicago. He also served as technical advisor to the producers of the motion picture Close Encounters of the Third Kind.
Dr Hynek is - 'The Man'!
