I was out walking my dog in larimer county colorado. i saw four ufos in pattern formation descend from the north at high speed and head south in a straight-line at an unbelievable speed. the ufos seemd to consist of a large glowing amber orb as the main body with two smaller same colored orbs positioned on the right and on the left in the front of the body. the second from the left seamed to be leading and by the way the craft seemed to accelerate before the others and slight inperfections in their flight pattern they seemed to be manned craft. if i had to make my best the craft stopped their decent at maybe 20-25k feet and then accelerated in a straight path from over my head to south and beyond the horizon in 2 or 3 seconds. this happened at approximately 18:56 mtn on 2/25/18. someone else had to of seen this.
