300Foot Telescope Collapse

At 9:43 p.m. EST on Tuesday the 15th of November 1988, the 300Foot 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 300Foot telescope resulted in the Green Bank Telescope Project.
