Twelve massive windows in the air traffic control tower at Baltimore-Washington International Thurgood Marshall Airport have been replaced after 30 years, an airport official said Thursday.
Each of the new windows weighs about 850 pounds and measures more than eight feet wide and eight feet tall, according to a statement from Jonathan Dean, a spokesman for the airport. All of the windows are 1.5 inches thick, he said.
The windows meet standards for strength, transparency, glare reduction and wind resistance, he said.
The window replacement work on the tower, which stands about 100 feet tall, took place in the early morning, and the height and design of the scaffold were "carefully planned to ensure full visibility for the air traffic controllers," Dean said.
The windows were replaced between Sept. 23 and Oct. 5, he said.
