As far as I know, there were problems with the heat protecting tiles of

space shuttle during the first flights. 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 ?

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).
