- The type of mission under discussion is one where re-entry is made from a
- ballistic trajectory at a maximum height of 125 miles. The tiles are still
- needed at this height because there is still a fair amount of heat generated
- and the aluminum skin of the shuttle has to be protected (aluminum loses its
- strength above 350 degrees F). It may not be the kind of heat generated from
- full-fledged re-entry from orbit, where the risk of burning up is far greater,
- but at those temperatures I would think it would still be preferable to have
- the tiles in place as an added safety factor rather than risking the aluminum
- skin.
