UFO In The Sky Changed Shape, Direction And Speed Over Denver, Colorado

According to eyewitness testimonial, on December 7, 2012 at 11:33 PM my wife and I were driving back
from the grocery store on our way home, when I pointed out a helicopter,
then saw an unusual blue-ish dot speeding up and going faster than the
helicopter, then my wife said "is this just another plane or helicopter" I
went ahead and pointed out that there was no blue and red lights on
them.
