Tiles were lost and the heat protection shield of the shuttle damaged. I am added to this mailing only recently, so I don't know if this subject has already been discussed. Since there was nothing to hear about this problem lately, I suppose it has been solved. Can anybody tell me how ? --- Ralf Eberhardt

I seem to recall that a product called Scotchgard was sprayed over the tiles after they were installed and dry. This prevented moisture from permeating the ceramic (the moisture turned to steam upon reentry therebye cracking the tiles and causeing them to blow off).
