UFO Danger Zone

Bob Pratt has spent over eighteen years researching the Brazilian UFO phenomenon. He has made eleven visits to a number of localities in the Brazilian countryside and investigated over two hundred cases, during which time he has interviewed over seventeen hundred people. The fruits of his labor are always intriguing, sometime frightening, and should give pause to those who would thoughtlessly maintain, without studying the complete score, that all our extraterresrial visitors are friendly and have out best interest at heart.
