In January 2020, a radioactive UFO flew over canada and triggered radiation sensors under its' flight path.
It emitted no sonic boom, had no witnesses and wasn't seen on civilian radar.
It didn't make the MUFON database. It wasn't talked about on any forums and there are no photos, video or audio evidence.
The DOE knows about it. The DIA also knows. So does the NRO, NORAD etc. So do some other countries since not every response could be hidden.
There exists a map and I have laid eyes on it - a map with sensor data betraying the flightpath and this map indicates how long it was over what area and when. Hopefully by the time I make this post (and I am taking my time), I'll have something that I can show you.
I can also determine it's average speed and with these sensors as a basis, determine some things about its' emission signature and profile.
This case will never become a part of UFOLogy or UFO history and it will likely be hidden for eternity.
and here's why: Everything about the event appeared as an attack , mostly of the hacker variety. The object moved so fast that it behaved like cyber attack. Further, it MAY have actively sought out the sensors in order to overfly them. Further, the object was so fast that it SEEMED like it was arriving at it's next destination before it had even left the one it was at. Like a loony toons character. Point in fact, this real world event would make a very useful training excercise - ideal even. Valuable lessons could be learned and yield great advantage.
I'll conclude with the MAP, which has been heavily neutered and shows the areas of interest, the sensors fluctuating and so forth.

I've made this post here for posterity. Just in Case.
Not that I doubt Your word, but I ponder knowing of an event that had no witnesses... Just some sensors going off? Is that it?
