On CNN this AM I saw footage of what could only have been burnthrough of the Starboard SRB. This was from NASA tracking footage taken to the north of the Cape, and impounded until yeterday evening. If this is found to be the cause, we should remember that analysis of earlier recovered SRB's showed evidence of burnthrough, and that it was stated at the time that only seconds had separated the flight vehicle from the catastrophe that we just witnessed. -- -David B.

With what now appears to be true, the right SRB seems to be a fault. I
seem to remember the on one of the original flights of the columbia, NASA
noted that at least one of the SRBs came very close to burning through the
outer skin. If this is true, where there ever any corrective measures
taken at the time?

P.S. Also, in seeing part of the original NASA select replay again, it
looks like the plum of fire on the right SRB is visible after the blow up.
Can someone verify this?dlnash@ut-ngp.UUCP (Donald L. Nash) (02/05/86)

I read an article in the local newspaper describing the the things which happened to the Challenger. That craft almost seemed cursed from the beginning, if one believes in such things. I don't remember if NASA took any corrective measures or not. Don Nash UUCP: ...!{ihnp4,allegra,seismo!ut-sally}!ut-ngp!dlnash APRA: dlnash@ngp.UTEXAS.EDU

Obviously they are interchangeable since the ET is always different. It would seem a waste to have two for every shuttle, but with redundancy and quick turn around times always high on NASA's list it would not surprise me. Does anyone know the history of the Challenger's SRB casings? Thanks -- Martin Van Ryswyk {dual,lll-crg,ucbvax}!ucdavis!deneb!ccs025 uucp ucdavis!deneb!ccs025@ucbvax.berkley.edu arpa

No they don't. The casings are broken down upon return into (I believe) 11 segemnts and shipped to Thiokol in Utah for refurb/reload. It is possible (probable) that segments are reused in order received at the cape. Having worked with NASA on a non-human rated program, I would be surprised in the extreme if there were not a thick paper trail following each and every segment (as well as all other parts) everywhere but on the mission itself. I'm sure that they are documented to the point that the weight of the paper may well equal the weight of the segment (only slightly facetious there). Lyle McElhaney ...hao!cisden!lmc
