Craft plummeted over Denver, CO, flashing orange and blue/green, flipping end over end, suddenly ascended rapidly out of sight

From an 11th floor rooftop near Cheeseman Park, Denver, CO, while looking SE toward Glendale, one perhaps saucer-shaped craft was seen rapidly descending, alternately blinking orange or green/blue light at perhaps 2-second intervals. It flipped rapidly during its descent, like a coin that had been tossed in the air. It suddenly stopped plummeting and at incredible speed zipped back and forth for a few seconds, then diagonally upward, until out of sight, above and south of the Tech Center in Greenwood Village.
