Countdown clock will resume in two minutes.
Once the countdown picks up, the Ground Launch Sequencer will be initiated. The computer program is located in a console in the Firing Room of the Complex 39 Launch Control Center. The GLS is the master of events through liftoff. During the last 9 minutes of the countdown, the computer will monitor as many as a thousand different systems and measurements to ensure that they do not fall out of any pre-determine red-line limits. At T-minus 31 seconds, the GLS will hand off to the onboard computers of Atlantis to complete their own automatic sequence of events through the final half minute of the countdown.
Well, nothing important, anyway....
You are about to launch.
Allow? Disallow?
