Clear and concise research by, in my humble opinion, one of the most clear-headed, fact based researchers on the topic of UFO's. As the title suggests, this book concentrates only on stories of CRASHED UFO's; no sightings, no abdution lore. The beef of the book concentrates on the five best cases of authentic crashes, then the book finishes with a chronology of alleged crashes and explinations (85% proven hoaxes, the rest are non-ufo related, insufficiant data, and a handfull of probable authentic cases. Probably one of the best source books for the serious researcher; loony unconditional believers probably won't like it, nor will hardened skeptics (debunkers by another name, who will grasp at anything to explain the authentic cases away).
There are only two cases presented in this book with which I have contention:
1) Aurora, Texas (1897). New information ,possibly since the publishing of this book, may lead this case to the point of authentication...there are two ways to find out for sure. A) although the heastone was stolen in the '70's, locate the grave of the "airship pilot" and have it exhumed (it's been in litigation for 10 years to do so). B) Open Proctor's well (where debries was allegedly thrown). If any remains,it would go a long way to proving either authentication or hoax.
2) Roswell. I still consider this the Trojen Horse (too much is made of this when there are better cases). Since the publication of this book, Glen Dennis' testimony has been proven, to the most part, to be fabrication. Would the Air Force fessed up that the wreckage was that of a rocket or experimental aircraft, this case would have for the most part dissapeared. The only things that keep Roswell on the "Unsolved" list is the testimony of the first hand witnesses of the metallic debris, and the length of rediculousness of the explinations that the Air Force continues to distribute.
Overall, one of the best books ever written about the topic of UFO crashes, and a must read for beginner and serious researcher alike.
