For the enlightenment of the masses a TR3B is simply a triangle shaped UFO. So now that that is out of the way, there are a great many reports of UFO encounters with man-made aerial vehicles such as jets. Few of those reports are ever released for public consumption. Even fewer are stories involving military jet encounters which end in the disappearance of planes and personnel. We were unfamiliar with this UFO event and are glad we can share with you.
