Finally the command was given: “Stand by!” Now, It would be a matter or minutes before the launch. Commands followed in quick succession. The flight recorder was switched on, the engines started up. There was not much noise at first. But, after the command “Main Engine” the noise and the vibration grew stronger. The final command came at 07:30 UT “Start!”
