Two Colorado witnesses watched a "metallic triangle-shaped" UFO shoot "straight up into the air" after following it at high speeds along Highway 96 near Pueblo, according to June 11, 2011, testimony from the Mutual UFO Network (MUFON) witness reporting database.
The object was reported as being silent and having red and purple flashing lights.
"The craft was about 900 to 1000 feet in the air at a speed of 150 plus mile per hour," the reporting witness stated. "The red and purple lights were flashing on and off at a fast rate which my friend and I thought was very odd. This craft didn't act nor did it look like an airplane or helicopter."
