Amazing to watch launch umbilical cords retract in the nick of time.
Rockets need to stay connected to their launch pad right to the last second, for fuel/gases, data and power. But the hot blast from the engines would cook the plumbing parts.
So they unplug, run away and hide in a safe room, slamming the door behind them. Ready to be used again.
