Unknown over Thornton, CO

The report, as filed

I was talking to my girlfriend on the telephone outside and looked over to the west. I saw what appeared to be a plane flying vertically but too slow for a an airplane. There were numerous lights...red, green, blue and white. The lights were flashing and vertical. It was traveling to North...approximately over the foothills (over Broomfield, CO) and continued north toward Ft. Collins. I looked to the north and saw the SAME light pattern on another object also moving north then east. I was narrating the events to my girlfriend and she said to take a picture. I did but the picture doesn't show the shape or colors. Then, I scanned the sky and saw three more to the northeast very high in the sky. I have a federal and military background and can estimate the altitude of the lights over Broomfield at around 600-1000 feet above ground level. The same pattern lights seen to the high northeastern sky had to have been at least 30K feet. Two of the pattern lights were masked by a thunderstorm cloud moving north. The top of that cloud could have been 40K in altitude. Hard to estimate with the lack of light.
