It seems a little ironic that the 1679 bit message sent skywards in 1974 contained a graphic and dimension of the telescope but will no longer exist if and when the message is received.

Is it just me or did anyone else think that the bottom of the dish was a solid concrete surface? I was surprised when I saw the pictures of the damaged dish and wondered how such a giant hole was created!
