Re: So why won't it melt?

A lot depends on the length of time that the heat is applied. An SR-71 must deal with heat over a long flight cruise time. A reentry vehicle has to deal with a hot environment over just a few minutes. While this doesn't make the heating problems go away, it does make them different.
