Chopper delivers new cooling units to Bldg. 1600 on Edwards
Workers from Siller Helicopters, Inc., attach cables to a new cooling unit to be lifted onto Bldg. 1600 April 7. The company's helicopter would dangle cable lines to be attached onto the old coolers, which were lifted off Bldg. 1600 and placed in a parking lot nearby. Workers then attached the cables to the new unit to be lifted onto the building. (U.S. Air Force photo by Kenji Thuloweit)
