re shuttle launch question from article c owcb n p world std com by tombaker world std com tom a baker in article c jlwx h cs cmu edu etrat ttacs ttu edu pack rat writes clear caution warning memory verify no unexpected errors i am wondering what an expected error might be sorry if this is a really dumb question but parity errors in memory or previously known conditions that were waivered yes that is an error but we already knew about it i d be curious as to what the real meaning of the quote is tom my understanding is that the expected errors are basically known bugs in the warning system software things are checked that don t have the right values in yet because they aren t set till after launch and suchlike rather than fix the code and possibly introduce new bugs they just tell the crew ok if you see a warning no before liftoff ignore it jonathan
