At 9:43 p.m. EST on Tuesday the 15th of November 1988, the 300-foot telescope in Green Bank collapsed. The collapse was due to the sudden failure of a key structural element -- a large gusset plate in the box girder assembly that formed the main support for the antenna.
The loss of the 300-Foot telescope resulted in the Green Bank Telescope Project.

Report and analysis of the collapseImmediately following the collapse, NSF and AUI convened a panel of experts in structural engineering to determine the causes. Their report may be read here:
History and Science with the 300 Foot TelescopeStories of the planning, construction, scientific accomplishements, and collapse of the 300 Foot telescope may be read in the recently-published book, "But it was Fun: the first 40 years of radio astronomy at Green Bank."
