Total time for this countdown is 21 minutes and 41 seconds and countdown starts exactly 2 minutes and 45 seconds before booster ignition "This makes for some nice audio leading up to the launch". But be sure to allow for this time in your launch window". The air-to-ground communication follows through the launch and continues for about another 10 and 1/2 minutes after MECO. All real, no commentary, strictly air-to-ground comms! I have also tossed in a new SSME sound for the launch as well. This package definately provides a whole new feel to the launch experience.Â
