Very. ANY relative motion in that bit of sky is odd. But these lights were very far away). I say that for two reasons 1) a plane higher on the horizon will very quickly fly past at a higher altitude and 2) That plane will either fly past or won’t be visible in the first place (because it is flying away. So let’s say it’s a plane at 20 miles that somehow never gets closer. Then I’d say that the relative vectors would be in the hundreds of knots. The “cork-screw” would be several miles in diameter. But these objects seemed to be more in the 100-200 mile range and extremely high. Whatever they are, they are not reflecting light. They are emitting very bright light, talking Klieg lights, afterburner or the most powerful LEDs I’ve ever seen. They are trying to be spotted.
