This add-on updates sound files for the Shuttle Fleet. These sounds (except ETSEP and Docking) were recorded from NASA TV during actual STS-117 mission to the International Space Station.
Notes:
Countdown sound timing is synchronized for launch with Ctrl +. To launch the shuttle, enter ITEM 777 in GPC MFD, press and hold Ctrl and + together at T-7 seconds.
Installation:
Simply unzip the archive into your Orbiter directory.
WARNING: This add-on will update your sound files. Backup your original sounds if you want to restore them later.
NOTE: Install the Shuttle Fleet before installing this add-on.
