Radar detecting UFOs is incredibly common and could be anything from an unusual bird migration(tightly packed flocks can appear as a single object on radar) to an unknown type of aircraft as all radar readings have to be compared to known radar profiles. If something with an unknown profile(such as a currently existing aircraft with a modified frame) is detected then of course it's going to be a UFO. Technically every single flying object detected, whether by radar or even by sight, starts off as a UFO. I fail to see what the significance is as just about any explanation, including multiple sensitive systems experiencing identical mechanical failures, is more likely than ETs.
The significance of course was that an object was detected by 2 independent radar systems, was confirmed (briefly) by a pilot, tailgated the pilot, and then zoomed off.
The reason I mentioned ETs in relation to this was that they were the original topic of the thread, not UFOs.
I understand. The reason why I raised this is because out of all fringe's crackpot assertions, this is the only one that actually has some evidence behind it. Does it make anything else he is asserting less woo? Nope. Even a crackpot can't be wrong all of the time (oooh I just made myself giggle).
