The Federal Aviation Administration (FAA) has launched a new and advanced 195ft air traffic control (ATC) tower at Reno-Tahoe International Airport in the US.
The airport's runways are considerably longer than they were when the old tower was built, which made it challenging for controllers to see aircraft on certain taxiways and runways.
The ATC tower includes advanced equipment such as multicolour radar displays, touch-screen voice communications and touch-screen work stations.
It features double-thick sunshades to prevent sun rays penetrating the 610ft² controller work area and two back-up power systems to help ensure uninterrupted operations.
The FAA built the new tower and a 10,000ft² base building at a cost of $29.4m.
Construction of the Reno-Tahoe Airport tower began in January 2008.
