Each tile is custom-formed to a specific shape. How do you have a "tile repair kit" under such circumstances?

Interesting question. In 1981 it would have been impossible. However, with computer driven cutters, it would be possible to make tiles to order. I'm sure the equipment would take up a lot of space, using it would take training, and once cut, how do you install them when the adhesive isn't designed to work except at precise temperatures?

OK, so you have as permanent cargo a tile fabrication facility and spare tiles.

Which, all told, would probably take up most of the payload volume...

Oh, you just use KRAZY GLUE! </sarcasm>
