In March 1985, a new air traffic control tower opened at the former Greater Pittsburgh International Airport terminal, becoming the tallest control tower in the country at the time. Today, the same 227-foot tower controls air traffic for Pittsburgh International Airport.

But where was air traffic controlled before then?

The Greater Pittsburgh International Airport terminal opened in 1952, and its original air traffic control tower was located on top of the highest point of the old terminal, above the airport’s rotunda area.

Light guns are visible above the air traffic controllers in the photo. Technology that still exists in air traffic towers today, light guns can be used to guide pilots as they maneuver their aircraft on the ground in cases of radio transmission failures, among other situations.

The original tower oversaw air traffic for Greater PIT until the new tower opened across the airfield in 1985. Planning and construction for the new, 20-story tower that stands as Pittsburgh International’s FAA tower today took about four years.
