ja but the only stresses on those already
heated/cooled materials are torsional, i.e.
NOT gravitic. During re-entry the gravitic
stresses reassert themselves dramatically
and if the thermal changes have weakened
anything then the gravitic stresses can be
enough to cause breakage.
sorry if i was unclear :-)
