STS-133 - Status Update on Space Shuttle Discovery / Expedition 26
Kind of makes one wonder if all the problems with the surface rtreatment of
the Sarj race ring might not be much the same issue, not enough attention to the actual treatment properties after the treatment.

I always thought the stringers were just a foam shape :-) Why was this never seen before, it seems to be a material and operational design issue as opposed to a manufacturing defect. With regards to tanking, an argument was made that the top of the stringers are under greater stress because it is at the bottom of the O2 tank and thus gets cooled much faster as the liquid O2 is dumped in there.. Couldn't they do some sort of pre-cooling of the bottom of the O2 tank to have a more gradual cooling of the structure until it reaches a temperature where dumping O2 at full rate would no longer be a problem ? pre cool, just start and stop tanking to condition the tank, like 5% fuel, then stop, wait a bit then fuel normally........ thats a low tech approach |

You know if the line hadnt leaked, the cracked foam wouldnt of been
found, the structural defect would of flown and today we could of still been discussing the loss of a 3rd orbiter and crew |
