300 Foot Telescope - After Collapse, 16 November 1988

Start Date:1988-11-16 Location:Green Bank, WV	Creator:Records of the NRAO Series:Photographs Series Unit:300 Foot Telescope Unit Type:Still Image Subject:Instruments--300 Foot Telescope Instruments--300 Foot Telescope--Collapse	Description: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. This is a photograph of the 300-Foot telescope taken on November 16, 1988 after the collapse. The loss of the 300-Foot telescope resulted in the Green Bank Telescope Project. [show more]
