I read about this EPA ruling long ago. Yet the media in all their thrashing around about the grounding NEVER mentions this! NEVER!

Is it true that NASA didn't change the foam at all for this launch? What on earth is different about this shuttle flight than the one that failed?

I read about this EPA ruling long ago. Yet the media in all their thrashing around about the grounding NEVER mentions this! NEVER! Fox 'n' Friends noted it prominently yesterday. But it should have been trumpeted from 1997, when the performance difference and risk associated with the performance difference were known.

What ever became of this. Was this proved to be real or fake?
http://www.starlitetechnologies.com/
Starlite is a revolutionary material able to withstand temperatures of 10000°C/18000°F ... nearly twice as hot as the surface of the sun ...
Starlite was invented by Maurice Ward and Starlite Technologies is here to bring this revolutionary material to the world.
According to the US Government "Ask a Scientist" website the highest known melting point for any substance is for diamonds at 3800°C/6872°F. Starlite can withstand nearly 3 times more heat, at least for a while... One difficulty in the manufacture of steel is its high melting point, about 1370°C/2500°F, which prevents the use of ordinary furnaces. Titanium melts at about 1660°C/3020°F... If heat is a problem for your company we have the solution that stands up powerfully to fire, lasers, and even atom bombs...
Starlite Plastic has fantastic applications in aerospace, military, and other industries ...

ERRR. Urban Myth Alert
Blame the greenies for many things, but *not* the Columbia foam. STS-107 used the old BX-250 foam made with CFC-11.
From the CAIB report, page 51:
Most of the External Tank is insulated with three types of spray-on foam. NCFI 24-124, a polyisocyanurate foam applied with blowing agent HCFC 141b hydrochlorofluorocarbon, is used on most areas of the liquid oxygen and liquid hydrogen tanks. NCFI 24-57, another polyisocyanurate foam applied with blowing agent HCFC 141b hydrochlorofluorocarbon, is used on the lower liquid hydrogen tank dome. BX-250, a polyurethane foam applied with CFC-11 chlorofluorocarbon, was used on domes, ramps, and areas where the foam is applied by hand. The foam types changed on External Tanks built after External Tank 93, which was used on STS-107, but these changes are beyond the scope of this section.
In other words: yes, the foam was changed... but for ETs *after* the one used for Columbia. Columbias ET used the same old freon-based blowing agent they've long used.
