Crater was programmed to calculate ice impact damage to the Saturn V.It was not optimised for lower mass debris damage to a tile.The big problem with crater and STS-107 was fully spelled out in the CAIB.The lack of upkeep/funding of the launch cameras gave the team using crater 'less' data than they needed.No one knew the 'exact' location of the debris strike. Was it the leading edge or just below near the landing gear door?What was the clocking angle of the rotating debris?What was the size/mass of the debris?Without good data in you do not get good data out.The engineers also knew that crater over-calculated damage AND we are just talking about foam here (dangerous combination).The precise angle of attack was unknown. The tests with the foam gun and leading edge samples that had flown 28 times had to be carried out multiple times with best-guesstimates on the angle of attack.The flagrant dis-regard for more analysis from the upper management (Linda Ham) caused in-part by intense schedule pressure resulted in the foam strike being classified as nothing more than a turn around issue post flight in the OPF.
But Mr. Hale tells us that "more analysis" wouldn't have mattered.

re nooneofconsequenceCareful. Nobody else uses the MSBLS system developed for shuttle. Many of the significant issues had to do with the ground equipment, the specific antenna arrangement, etc. I seriously doubt that any other airframe used (uses?) that system.

It is not your fault.I didn't really read it as blaming JSC per se, but more so the city of Houston and the state of Texas. I think he was touching on topics greater than landing a shuttle too. I took the main points to be lack of future programs and projects, and not doing anything about it. I took it as trying to light a fire to do something about it. Just my take though.

Texas will have to keep up the fight for SLS, as well as any and all future NASA programs. Otherwise Hale's vision of a mothballed JSC may just be closer to becoming reality than we all think.
