This is Apollo Saturn launch control
T minus 1 hour, 50 minutes, 55 seconds and counting
We're proceeding with the countdown with the Apollo 11 mission
At this time and it's going satisfactorily
At this point, the spacecraft commander Neil Armstrong
In the process of working the emergency detection system test
This is a check of the emergency detection system
Working with the launch crew here in the firing room
And also the spacecraft team in the control rooms
Back at the manned spacecraft operations building
Here at the Kennedy space center
All going well with these tests at the present time
We're flowing hydrogen back into the third stage
Of the Saturn V launch vehicle
After having difficulty with that leaking valve
It appears that we are bypassing the use of the valve directly
In loading the hydrogen aboard
But we are getting the hydrogen back in to replenish the supply
All appears to be going well at this time
Weather is go, we're coming up on 1 hour and 50 minutes
This is Kennedy launch control (launch control [2x])
Control [3x]
