Its amazing to me that some regular dude can duct tape his cellphone to his head, jump out of an airplane, and record incredible video in amazing color detail with nice stablized video that the individual frames can show tiny details like children playing in a playground from 10,000 feet up. But the United States government in the most advanced aircraft ever built can only get grainy black-n-white choppy shaky video of one of these UFOs.
