I never realized how well the pit beneath it captured all that fiery mess. Is it simply the thrust of the engines that is causing the initial burst of flame to get sucked back down like that?

Also, where the hell did all that energy go? To continuously draft that air through, there must have been some huge fucking vents in the ground somewhere, right?

Yea, the flame pit has an exit to one side to divert the exhaust, otherwise one would think it would be able to come back up at the engines and we all know how that works out..

I wouldn't waste a time travel on it since I can see it via youtube.

I never saw the Saturn V liftoff but did see the 2nd shuttle launch from an on-base position, about 4 miles away. The ground shaking under you feet and the enormous rumbling are something that cannot be really experienced via a YT vid or even an IMAX screen. Another Saturn V fact, " All told, a Saturn V churned out more power than 85 Hoover Dams or, if you prefer, enough energy to light up New York City for 75 minutes."....

Just to add one.

Yeah, there is a tunnel underneath porting exhaust out the side.

Murica, bitch.

Lotta water dumping there :)

Nice shot from inside the separated booster as the 3rd stage ignites. And to think they engineered the ability to gimbal all 5 of the F1 engines to lean it away from the tower a few degrees for safety, must have been one hell of a hydraulic system to handle 8.5 million lbs of thrust!..

I was lucky enough to watch a shuttle launch when I was young. I played drums in school but the rumble I felt in my chest that day was of pure raw power.

Thanks for posting the link :thumbsup:

I was lucky enough to see all the Saturn launches, as well as all the Shuttle launches.
I've also seen all the Mercury and Gemini launches.

Nothing has ever compared to the nighttime Saturn V launch (Apollo 17), the shuttle night launches weren't as bright or as loud IMO.
Amazingly all the Saturn V's were louder than the Shuttles and for a longer time, as they accelerated slower.

But Apollo 4 was the loudest, it was before the sound suppression system was fully implemented and it shook your whole body (not rumbled, but actually physically shook).
Even though I had just started high school, it scared the bejeebus outa me.
None of us knew that was going to happen or that it was ok.

From then on the water dump system was fully in place.
For those that aren't aware the "water dump" is for sound suppression, not for cooling the launch pad.
The pad has it's own protection and the water adds virtually nothing to cooling at those temps, as it flashes instantly to steam.

Hopefully I'll still be around for the Mars and asteroid launches.

Good stuff. The narrator actually knows what he's talking about which helps. All the water flashing to steam was amazing.

Lucky you!, amazingly, despite the enormous complexity of these machines all of the Saturn V launches went off without a hitch save #13 which did have an engine shutdown early but was easily remedied by burning the remaining 4 a little longer but as we all know the real trouble for #13 was just hours away..

If you watch this video, around the 4:16 mark (3 seconds after the url start time I'm linking), you'll see the flame blasting off to the side. As BUTCH1 said, they vented all that flame off to one side, specifically so that it wouldn't interfere with the launch of the rocket.

Apollo 11 liftoff

It's amazing. It's been over 45 years since the launch of Apollo 11, and it still sends shivers up and down my spine to watch it. I was 7 years old in 1969, and my mother made sure that my siblings and I watched this bit of history unfold on TV. It's still magical to watch, after all this time.

Really too bad that the president didn't think to spend a trillion dollars on getting us back to the moon again, instead of on "shovel ready" jobs. :rolleyes:
