Northern Colorado Regional Airport tests one-of-a-kind virtual tower

As 13 giant television screens monitor every movement, a Sun Country  Boeing 737 barrels down the runway at Northern Colorado Regional Airport, whisking the Colorado State University football team to Reno, Nevada, for a Mountain West showdown.  Behind three workstations, controllers zoom in and out on their screens – keeping one eye on the sky, the other on the aircraft as it accelerates, lifting its nose toward the heavens.
