I was having my morning coffee, I generally look out my window while I'm doing that. I looked up and I asked my friend if they could see that weird smoke trails. The trails were long at first and you could see that there was a direction change in the upper atmosphere. As this UFO Sighting got lower to the ground, I would say within 1,500 feet, the UFOs slowly started changing directions and started heading east toward Buckley Air Force Base. There was no sound, no odor no strange electromagnetic sensations. The UFOs did not appear to be in a hurry and they maintained a straight heading. Had I not looked at them directly, I probably would have imagined them to be a chemtrail coming from an aircraft. However all three of these maintained a perfect formation until they're out of sight. mufon cms# 113475 Denver Colorado 1/31/21 This Region has had 2,651 Reported UFO Sightings to date.
