SIGHTING: PARKER, COLORADO (UNITED STATES)

Witness Testimony

"At 6:10pm on dec 8th 2017 in parker, co, a group of us heard a loud pulsating and rumbling sound shaking a steal structured building we were sitting in. it had gotten louder and louder and lasting for more than half a minute. this was unusual as airplanes that flew over that building even at low altitudes never made that loud of a sound. i decided to go outside to see what was going on, as it seemed like a giant tractor was about to plow into the building. when i came out, my eyes was adjusting to the dark skies, and did not see anything, but the sound was deafening. as i scanned the sky i first noticed blinking red/blue lights common to planes or helicopter, but i couldn't tell because of the pulsating noise. as my eyes adjusted after a few seconds, i notice that the blinking red/blue lights aircraft was in fact following a light blue orb just ahead of it. the aircraft and blue orb was making a beeline from a nw to se direction directly over my head within 15-25 seconds, both the aircraft and blue orb was out of sight and the noise left with it. it seems whoever was chasing the blue orb knows what's going on as it was obvious that the plane or helicopter was following that blue orb!"
