Be sure to also see Green, Unknown Object Encountered over Colorado, another interesting case from the state.
Breckenridge - 07-16-12
A lighted object is seen falling toward the earth, then reversing its course back up into the sky. At 9:43 PM, as I drove north on Airport Road in Breckenridge I saw a large light falling from northeast to southwest through the northern sky.
The light fell predictably (as if it was a shooting star), but then it changed colors from white to red to green. After the light fell below the tree line, it reversed its course and came back up into the sky before it fell back to Earth again (it was more pink in color at that time).
This reverse pattern is what leads me to believe it wasn't a meteor or comet. I drove along looking for people who may have been shooting fireworks, but there is a fire ban in Breckenridge and this light action was seen along the highway where shooting fireworks would be quite risky. I couldn't find any people or any action of sorts; nothing that could account for what I saw
I must tell you that I often watch the skies, and I see things with an open mind. I have seen a number of comets and meteorites come down to Earth, but this was totally different. As I watched the falling object, I naturally expected it to continue its trajectory toward the ground, and I was shocked when I saw it suddenly change course. I can say with 100% certainty that whatever this was, was under some type of intelligent control.
Denver - 06-20-12
A triangular shaped UFO was seen for 15 seconds over Denver. At approximately 8:15 PM, mountain time on Wednesday, I saw an unidentified flying object. At the time, there was a weather system moving from the south to the north.
The leading edge of the system had broken up into small clouds creating small gaps of clear sky. I saw what I thought at first was an airliner. I quickly realized this object was moving too fast to be a passenger plane. However, it was at approximately the same height as a high-flying airliner, somewhere in the 25,000 ft. range.
The object itself was white, and of a triangular shape. The leading point of the object was farther away from the 2 aft points making an elongated triangle. This object was moving very fast, definitely faster than an airliner. There was no sound.
The light was very good. The sun was at a great angle to reflect off the object while being behind the clouds of the weather system. There was no trail or aura seen.
I am an enthusiast of military aircraft. I know the difference in shape of most military craft. This was not a fighter jet. This was not an F-117 or B2 bomber. I have a physical every year and my eye sight is checked at that time. It has been checked at 20-10 vision. This is better than 20-20.
I can see very well. If I had to guess I would say this object was man-made. I would say it is a lifting body possibly a space plane, a plane capable of flying from ground to orbit to back. I would guess it is the new spy plane to replace the SR-71 blackbird.
