I'm looking for a link to the actual report to see if the "environmentally friendly" reformulation of the insulating foam is mentioned.

The liberal golden calf will almost certainly not be blamed. And if so, hidden away in passing.

You win again!

All roads lead back to r12, which the original foam & it's adhesive was based on(a known perfect product was replaced by a known inferior product to support the Freon scam, end of story...., or maybe a beginning?)

I'm looking for a link to the actual report to see if the "environmentally friendly" reformulation of the insulating foam is mentioned.

I'm sorry to report that the following small paragraph in Chapter 3 (1.6Mb .pdf) is the only mention of the change in the foam. (I hope some FReeper can prove me wrong on this, but I can't find any other mention at all).

Throughout the history of the External Tank, factors unrelated to the insulation process have caused foam chemistry changes (Environmental Protection Agency regulations and material availability, for example). The most recent changes resulted from modifications to governmental regulations of chlorofluorocarbons.

...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.

That's it? Or is there another "section"?
