Detailed account of eye witness reports, interviews of military & civilian accounts of the events of July 1947 when "something not of this world" crashed in a field near Roswell NM. Very interesting, detailed nicely, easy to read.
One of the best researched books on the topic. They tracked down everyone that could find that was not scared of being killed by the military, and did a step by step investigation. This is the real thing! Even if you have read many of the UFO books out there, this is the real story!
