Re: black project, here’s no way to hide a Saturn V launch. The only manmade sound louder is (or perhaps was, since the Shuttle has more pop) detonation of an atomic bomb.

Yeah. I vividly remember watching the first Saturn V launch on TV, only to be distracted (and pulled outside) by hearing the launch live, loud enough to overwhelm the volume on the TV. From 125 miles away...

Heh... 23,000 pounds of fuel consumed per second in five regeneratively cooled engines that could have continued to fire at that rate for at least sixty minutes (given enough fuel), and as they quoted in Apollo 13, “That is how we do THAT.”
