This has been the first book I have read which tries to explain many of the famous documented UFO cases of the world as government test flights of secret new aircraft and malicious covert agency tinkering of foreign state radars. After finishing the book I felt entertained and also reasonably willing to accept the premise that most if not all UFOs are of human origin. Decide for yourself.
In brief this has been a successful buy. My son of 19 months has happily played in this tent for the past few months and at some stages the whole family including my dog have managed to squeeze inside. The only real negative is that it is not made of the best quality but for the price I don't feel too hard done by.
