What: Republic/Frontier Airlines Embraer ERJ-190 en route from Omaha,NE to Denver,CO
What: Skywest Airlines Canadair CRJ-200, flight OO-6764 from Lincoln,NE to Denver,CO
On Nov. 23 at 7 a.m. the two jets were approaching Denver, flying parallel to each other. The Frontier Jet was supposed to line up with a string of planes following Skywest.
Controllers gave the Frontier jet an incorrect heading and they made a u turn that put them in a collision path, a mile-and-a-half away and 200 feet above and closing fast
Collision avoidance systems engaged aboard the jets, forcing the pilots into evasive maneuvers. The FAA is, of course, investigating.
