I was amazed by the perfect timing. I realized, if you listen closely, there is commentary audio feed from the launch with countdown.

So knowing, the engines starts 3 seconds before liftoff, he was able to time the speech.

I saw this clip dozen of times, and only after keeping attention I realized this.

So with the cut technique, it seems like seamless feature, and that's the magic of the TV. Nevertheless amazing delivery.
