5 miles from the space shuttle launch. Had no idea what to expect. I wondered if it would sound like an F-15 w/ after burners flying in the distance. Instead, the 10 or so seconds it took for the sound to arrive was a pant leg flapping 20 to 30Hz. not painful to the ears mind you, just an exciting pleasurable 45 seconds of widow shaking subwoofer bliss!

From NASA:
"The three Space Shuttle Main Engines, in conjunction with the Solid Rocket Boosters, provide the thrust to lift the Orbiter off the ground for the initial ascent. The main engines continue to operate for 8.5 minutes after launch, the duration of the Shuttle's powered flight. "
"As the Shuttle accelerates, the main engines burn a half-million gallons of liquid propellant provided by the large, orange external fuel tank. The main engines burn liquid hydrogen -- the second coldest liquid on Earth at minus 423 degrees Fahrenheit (minus 252.8 degrees Celsius) -- and liquid oxygen."
"The engines' exhaust is primarily water vapor as the hydrogen and oxygen combine. As they push the Shuttle toward orbit, the engines consume liquid fuel at a rate that would drain an average family swimming pool in under 25 seconds generating over 37 million horsepower."
"over 37 million horsepower"
Your neighbors called. They like your music.
Obviously, they worked with Chevrolet!"over 37 million horsepower"
Not all vegetables make good leaders.

In 1985 I was at the last shuttle launch before the one that blew up on take off. Looks like we were about the same position. I couldn't believe how loud it was. I was wondering why some people had headphones/ear protectors. Taking the tour is GREAT too. Spent all day there with the family.
Apparently, this is the reason for the water sprayed at/into the base of the pad @ ignition. Not as one might think, to cool or put out any 'fire' per se, but to attenuate the sound and prevent damage to the pad etc.
You are correct... I was with my cousin at the launch who's worked at Nasa for 30 yrs. He used to work recovery in the Indian ocean where they collect the two boosters and reuse them. The orange fuel cell also falls there but in a thousand pieces. It's still collected because they float.

Wow, the boosters make it all the way over there?
