On May 8, 2020, the researcher and YouTuber Mrmb333, he noticed a huge radar anomaly and thought it was just an incorrect signature of the Dopler Radar, until he realized that it was over 500 miles wide and moved from northern Idaho to the Saskatchewan / Alberta border in a split second.
Given the incredible speed that jumped from southwest to northeast, it must have been something other than a flock of birds or a cloudy system. While it remains unclear, could it be that the weather radar reflected on something that came from space? Maybe it was a huge UFO?
