Powerful rocket engines

[harm_less]

Did you follow the Apollo programme? 

The rockets on the Apollo 11 were powerful. The five┬áengines created┬ámore power than 85 hoover dams.┬áThe┬ásound of the launch was so intense that they had to dump 3m litres of water onto the pad every minute just to dampen the sound waves so they couldnÔÇÖt bounce back up and destroy the rocket. They have a large water tank near the launch pad to supply the water.

Imagine then being one of the astronauts aboard Apollo 11. would have to have had a lot of faith in the design and construction of the craft and its support structures.
