A 2 piece 30"/F4.6 OMI mirror. The mirror split into 2 equal pieces after the trailer it was being transported in hit a pothole on a dirt road. There was a very minor chip on the back of the mirror, which was never going to be a problem but the mirror split right where the chip was.

That was a $30,000 plus mirror, in a $60,000 plus SDM Telescope.
