Both shuttles that blew up were launched under cold weather conditions
in January. Then they launched this one during a heat wave. Maybe they
should try to launch under moderate conditions, say during March or
September.


It's not the ground temp,its moisture that accululates in voids in the foam
that expands under aerodynamic heating during ascent that blows off chunks
of foam.
