eSkeptic book review snip:
In an interesting essay included in the book titled Militant Agnosticism and the UFO Taboo, two political scientists, Alexander Wendt and Raymond Duvall, advance a theory as to why the U.S. government has supposedly been less than forthcoming on the UFO question. As they point out, skeptics cite a number of seemingly intractable obstacles to interstellar travel to argue against the extraterrestrial hypothesis. Nevertheless, Wendt and Duvall argue that the origins of the UFO taboo are political, not scientific

eSkeptic book review snip:
Kean endorses Wendts and Duvalls call for a militant agnosticism in pursuit of UFO investigations. By agnostic, they mean not rushing to ascribe UFOs to extraterrestrial sources. If, however, the eyewitness accounts presented in Keans book are to be believed, then one would be hard pressed to conclude otherwise. Other explanations proffered in the past would be at least, or even more, mind-boggling, such as time travelers, Nazi flying saucers from underground bases in Antarctica, or visitors from other dimensions. What is most compelling about Keans study is the number of seemingly credible and authoritative first person sources who go on the record for her with their positions on UFOs. None of them claimed to have experienced any repercussions from the government or men-in-black visitations.
