Locating the Gusset Plate: The cause of the 300-foot’s collapse

300-foot telescope and location of failed gusset plate

After the investigation to determine the cause of the 300-foot telescope’s collapse on November 15, 1988, engineers pinpointed the location of the sheared metal gusset plate they found in the wreckage. The gusset plate is a thick sheet of steel used to hold and connect the beams of the telescope.
