The Perimeter of a Telescope

The Green Bank Observatory 300 foot telescope collapsed November 15th 1988. The dish is five stories up from the ground and its diameter is a hundred meters with this massive reflector arm that stretches up like another 70 feet. There are three main points of interest at the observatory, including what looks like a big pile of broken machinery or something. And then of course, there's the telescope itself, which is just like awe inspiring piece of technology.
