| Mission Control Answers Your Questions |
 From: Sarah, of Antioch, Ill.
To: Jeff Hanley, flight director Question: What does it mean when, during the launch procedure, you say that there are "no unexpected errors"? Answer: At T minus 2 minutes, 30 seconds, the crewmembers clear the caution and warning system memory for ascent. When they do this, they verify that there are no unaccounted for error messages that have been logged. If everything is normal, the crew reports "no unexpected errors." |
