Necratoid spoke as Zarathustra
I hate to break your little conspiracy driven world that the new stuff (CFC free) is the problem; but the first fifty flights of the shuttle noted tile damage from foam debris on liftoff (25 tiles damaged on the average). In the 112 flights of the shuttle program, foam was shed in 70 of them, and tiles were damaged every single time. The new stuff was not problem free either, and after issues in 1997, the formula was altered and is still being fine tuned. Tiles on the shuttle were damaged by foam breakaway before the switch and after the switch, it is an operational constant of the shuttle program.
During the Second World War, the boffins in aviation went to great lengths to examine planes that returned; being quite clever, their research was not into what was hit, but what wasnt. Planes that get hit in certain areas but made it back tell you quite a bit about essential and non-essential damage. In the case of the shuttle the danger of tile damage varies depending on what was hit, and where. If you have tile failure in a critical location during re-entry, it will destroy the shuttle. This is the operational reality and it has been the operational reality since the program began. Thus the recommendations of the panel into the recent shuttle disaster recommended that several new procedures to mitigate the known risk be undertaken better observation of the shuttle during liftoff and while in orbit, better testing for wing panels, and an inspection and repair plan for astronauts in orbit.

Some like the foam they use on space shuttles is so much worse, that it managed to damage a space shuttle lethally. (Yes, other factors are involved, but the kill shot was a rock like chunk of the non-CFC foam damaging the tile.) That the foam isn't a CFC based one doesn't bug me... its the crumblely feature of the new stuff that does.
