Would a "weather balloon" they later claimed, make a crater that big.
Weather baloon definitely not. But heavy artillery shell or missile that seems to be some standard anti-weather-balloon weapon in US army would. :)
Unfortunately, neither crater itself, neither fact that it couldn't be a result of weather balloon fall could be a proof of UFO. There have to be something more, that will definitely exclude any explanation other than alien spaceship.
