Anyway can anyone guess how fast a shuttle has to accelerate to get to 17,000 mph in 8 minutes?
No guess here:
0.001 miles/s2

Calculate that to miles per hour.
*sigh* you can't measure an acceleration in miles per hour. You still don't understand.
He linked to the acceleration calculator, so if you want different units just do it yourself.
You lot won't do it because it renders your rockets a total pile of crap for their size and for human travel.
You all know fine well that no rocket that size, nor human could survive even a portion of the speeds they allegedly attain.
Anyone out there with a rational brain, do the maths. No need for comlicated bollocks or anything. Just do the maths for how a rocket can accelerate to 17,000 mph in 8 minutes but don't allow yourself to be duped by silly mathematical workings.
Here's a tip for those that can think.
For a rocket to attain a speed of 17,000 mph for supposed entry into orbit our of Earth's atmosphere, it must always accelerate.
Now keep that in your heads the next time you accelerate from 0 to 60 mph on anything and feel the force upon you. Look at dragsters accelerating on a track and basically falling apart after seconds at times.
How many of you have taxied on a runway in a plane then been pushed back into your seat as the plance goes into full on acceleration to lift off? many, right?
Now this is only 200 mph or so and also it's basically horizontal with a slight incline as it goes into the sky. Once it levels out after
full thrust, it keeps a constant speed, so all is well.
However, a ballistic rocket is a different kettle of fish, because a rocket cannot stop accelerating if it needs to reach a certain speed, so the force acting on it and the supposed human occupants would render them useless, or to put it simply, it would break the rocket apart and would have already killed the occupants very early on.
There's no way around this. This is what would happen if these speeds were to be attempted.
Did you know that they say they don't allow a shuttle launch in the rain because if they did, they say that the rain would be like bullets hitting the shuttle and would break it apart. Of course, it's a made up story where the shuttle is concerned, because the shuttle is not a real space vehicle, yet there's truth in the story in terms of the speeds mentioned, because that's most probably what it would be like with rain.
Just sittin in your own home looking out of your window with rain being smashed against it at 90 mph makes you think the windows going to shatter.
People just can't visualise 17,000 mph. They think it's nothing because they are made to believe it's no big deal where space vehicles are mentioned.
Let's get a bit real here.
A plane uses full thrust to get airborne. Basically it has nothing left but the lift of the wings to basically glide higher at a slight angle where the air becomes thinner and the strain on the turbines becomes less stressful, meaning faster speeds can be attained.
In a rocket, it has to use full thrust all of the time. No throttling down and all that clap trap. It's full throttle and you're off.
So the real question should be. How does a rocket accelerate all of the time, anyway?
It should simply springboard from the launch pad and carry on into the sky at that speed, vertically. This is in reality though, but as we know, we are not dealing with reality in the space game, are we?
Remember, N.A.S.A rockets do not have gears, so to gain height they have to increase throttle or shall I say thrust.
The major problem with this is, they don't have any increased thrust, because they are at full thrust on lift off. Anyone see what I mean here? All you roundies, don't bother answering this, I'm not interested in your clap trap.
The best any rocket can do is to go ballistic for a short period before arcing right back to Earth, expending their fuel in minutes, which is exactly what they do if anyone cares to look.
