It's the Freon Virginia!

After surfing the blogs today and listening to talk radio this morning we have the culprit on the foam. In 1997 Freon was taken out of the process to apply the foam to the external fuel tank. To be "Green" and appease the EPA, NASA changed its application process. From a 1997 flight of the Shuttle had 308 ceramic tiles damaged versus the usual 40 tiles damaged per flight. OK NASA get a waver and get the fleet rolling again! The International Space Station will be shut down if we don't get the shuttle flying again. (HT Whizbag , Mikes Noise and Instapundit.
