This stuff gets so old! Filled with half-truths, and just look at the "experts" they bring on, and they look like just weird people! Seriously, these folks often look like they were cast by The X-Files!"
At one point in this episode, these folks who have no military experience start spouting performance stats they probably Googled about military aircraft defense flares and then totally ignore any effect on those flares caused by wind or other environmental conditions.
They always make a big deal about "UFOs are real!", as if that really means anything. "UFO" stands for Unidentified Flying Object, nothing more, nothing less. It is NOT synonymous with extraterrestrial. It is simply an object that has been observed, flying in the sky, that the observer couldn't identify what it was. Many now famous military aircraft were previously reported as UFOs. Bringing in a bunch of folks who look like they were picked up at a seance, or a homeless shelter doesn't lend credibility.
Sadly, the "History" channel, is just that, history!
