The broad themes of the Project Blue Book show are grounded in the now established facts of the early UFO era. The US government at that time was desperate to figure out what UFOs were and the level of threat they represented, while also reassuring the public that they were nothing to be concerned about. Meanwhile, because UFOs actually were mysterious and alarming, the government engaged in extensive surveillance and penetration of civilian UFO research organizations.
Hynek was well-regarded and highly capable as a physicist. He was hired by the Air Force to pick apart and publicly debunk the weak or marginal UFO cases that the Air Force sent him while posing as if the official Project Blue Book was a genuine and thorough effort to find the truth. Meanwhile, the most compelling UFO cases were secretly reported to an unknown group via separate channels of communication and kept from Hynek and the public.
In later years, Hynek was said to privately complain that even after all that he did for the Air Force, they never trusted him with the good cases and what they secretly knew about UFOs. As to why Hynek put up with such an arrangement, he referred to the wife and five children had to support -- including four sons bound for college.
After Hynek's Air Force contract ran out, he continued to research the UFO subject via a foundation he set up. Free of the restraints of the official Project Blue Book, Hynek revealed that he had gradually become a believer in UFOs while remaining scientifically grounded. This is how Hynek is now mostly remembered. It is said that the US military and government officials continued to privately seek his advice up until his death.
