begin quoted material The ET Saga Several years ago (in the 90's) the EPA and a past Administrator demanded the shuttle program remove Freon from the primary ET foam (CPR-488). From the moment NASA implemented the change, lots of foam was flying off the ET. Now we had a new problem. Thought is now being given to going back to the old CPR-488 foam. ET Hints From MSFC Inside word from MSFC is the largest piece of foam that came off Discovery's ET is the result of work conducted in the forward end of the area that failed and may not be an issue requiring redesign. Revised maintenance and close out standards may take care of the risk. end quoted material "The largest piece of foam," eh? Got a photo of it? Challenger's Ghost |
