When I was in the Navy, during the mid 90’s, I watched these things take off and do training tests or whatever they did. We watched them for hours. It occurred to me, watching them in perfect daylight and with a understanding of what I was watching, that if I didn’t know what that was it could have easily been a UFO. And ever since then when someone tells me that they might have seen a UFO I tell them about watching that airplane and how UFO it looked taking off and doing maneuvers. Its shape and speed make it such a bizarre thing to see.
