I have but one question. If a weather ballon fell in your back yard, do you think the military, then or now, would spend all the time, money and energy validating it?
Wouldn't it be very obvious it was a weather balloon? Why the secrecy? Why the blockades, the obvious panic displayed by the government?
It was apparant that balloons fell to the earth at this time, but there is not one case documented that the government went to such an EXTREME to note that it was a balloon and not an UFO.
Read the book and see what you see.
