One for the space nuts; A nice collection of quality footage narrated by a couple of NASA engineers.
that was worth watching! Thanks!
I worked on those bad boys.
You should try standing just a few miles away when they light one off!
It sounds like a 1000,000 horsepower top fuel dragster.
Very cool. What was most evident was the joy and pride the narrators had four the shuttles.
I didn't expect to see the whole video.
My son and I stood on the north end of Cocoa Beach in April 1985 and saw the Discovery launch that took Sen. Jake Garn into orbit. It was a day of high overcast, so we didn't get to see a whole lot of the launch before the shuttle went into the clouds. I turned to my son and made some cheesy comment about having driven all the way over here from Orlando just to see this little bit of action. We then turned around to head back to the car when the sound hit.
I spent 36 years fixing fighter jets--wish I had a nickel for every time I've heard an afterburner--and I have never in my life before or since literally felt the sand on the beach shake from the noise of this launch. As God is my witness, the beach shook for about two minutes and the sound rumbled for ten minutes!! The noise alone made the trip worth it.
If one afterburning fighter engine puts out 25,000 lbs of thrust (this for the sake of the math here...) then it takes 40 engines to put out 1,000,000 lbs of thrust. The shuttle has about 7,000,000 lbs of thrust. That's the equivalent of 280 fighter jets! No wonder it's loud!
I would highly recommend that any time you get an opportunity to see a space shot, take it. Even if it's an unmanned shot, it's still totally awesome.
I learned a few things about the shuttle today. Thanks, w3stie, for posting this video.
This is available on Apple's ITunes store. I have it on my IPad and I watch it often.
where did you work?? I was the Forward Shop Lead in Highbay1
I'm a huge space nut. In the article below that is linked, I learned that during launch, 350,000 US gallons (1,300,000 L) of water are poured onto the pad in 41 seconds. That's the steam that you see during launches. Here's a great article on Wiki about the shuttle program:

I've stood under an orbiter trainer at KSC and seen Enterprise at Udvar-Hazy. That's a pretty good-sized airplane! Gotta go back and see Discovery now.
That's what this country could do back when we used to be a superpower. I saw the first moon launch in 69 from Cape Kennedy. We stayed at my Aunt's house 25 minutes away. There were so many Americans who came to watch the launch that it took us 7 1/2 hours to get back to her house.
The closest I've come to that loud was a Harrier jet demonstration, which I'm sure comes nowhere close to a launch. Can you imagine what the sound must be like on the launch pad
