Our call sign is Excaliber. Your scheduled departure time is 0730 local, so please be in the suit prepration room prior to 06:00 local time. so that we can prebreath oxygen to prevent bends if we were to have a decompression while in flight. Our shuttle is OV-110 and we will weigh in at about 7.2 million pounds prior to liftoff, including fuel and oxidizer. The launch and support crews have informed me that we are "A OK" for the launch as now scheduled. Have a safe flight.
