Now imagine the power of a Saturn 5 rocket
Speaking of pwerful engines, when Apollo 4 took off with the first full-up Saturn 5 rocket beneath it, the ABC News building roof over 3 miles from the launch pad got blown off by the force of the launch blast.
They said if a Saturn 5 ever exploded on the pad, it would be like a mini-nuclear bomb.
Factoid 2 - Saturn 5's got one INCH per gallon of fuel.
