Backup structure of the 140-foot telescope

The 266-ton dish superstructure (BUS) for the 140-foot (43-meter) telescope in Green Bank, West Virginia has been completely assembled and awaits hauling onto the telescope’s yoke in November, 1964. The maneuver took longer than expected: the superstructure was dropped accidentally during a derrick failure.
