The rocket-powered X-15 was the fastest powered, manned aircraft, reaching a top speed of 7,274 km/h (4,510 mph) on October 3, 1967. However, it was a rocket-powered test aircraft incapable of taking off from the ground and was launched at altitude from a carrier aircraft and operated at the margins of the atmosphere.

Not sure its the fastest ever as I never checked space rockets but this has got to be close

Interesting point Bob!
Are not we all travelling the fastest at the same time as the earth hurtles around the solar system at 64,000 miles per hour?! Everyone got their seat belts on?

Hi,there
Not sure about all this
Perhaps some "Oldie Techie" can tell the story:
Chuck Yeager set the World Record for the highest parachute jump(I think about 100,000 feet!)
Set the World Record for the fastest man without a plane.
And also set the World Record as the first man to go through the Sound barrier without a plane.(thin air!)
All in ONE jump!
Saw it on UK TV a long time ago where Chuck Yeager was interviewed on a programme about the Sound Barrier.
Chuck also told a story about when he was doing "static tests" on a plane
The plane exploded behind his seat.
In all this confusion some of the Coolant Fluid ran on to the lower part of his body
The following day's Headline was:


X-5 Explodes!....Pilot Wets pants!

the fellas on the Saturn 5 rocket are supposed to have travelled faster than any other human.
When they we're travelling towards the moon, their speed was 10km/s!!

thats also...
600km in a minute
or...
36000km/h


thats CRAAAZY speed :D:D:D:D





there was also a chap from the american airforce who did a skidive from the upper atmospher and reached 714 mph during free fall (with only breathing apparatus and parachute etc on)... although some French muppet is trying to beat it soon.... http://www.space.com/news/060713_big_jump.html


hope thats satisfied you

(unless you count the speed we're travelling around the sun!)

in accordance to Wikipedia, '... in accordance to the 2001 Guinness international archives Apollo 10 has the record for the optimum speed attained via a manned motor vehicle: 39,897 km/h (11.08 km/s or 24,791 mph). the cost record became set in the time of the return from the Moon on 26 could 1969. ...'

Hi Wondering,
Without hopefully getting to silly-tech, it is back to good old relativity.
What are you moving relative to what ?
I suppose approx. 27,500 mph for those folks heading for lunar orbit insertion, relative to a point on the Earths' surface is tops, although that wears off down to about 3500mph at the "Lagrange" point, then speeds up a lot as the moon takes over.
Relative to flying in atmospher over the surface, it would be about Mach 6, or equivelent to about 4500 mph at sea level.
I personally have not gone above around 1700mph, thanks to good old Concorde, but having played ping pong in a train travelling at 80mph, if I add or subtract the speed of the ball, to someone at the track-side, it would be moving at either 40mph, or 120mph.
Not taking into account that the Earths' surface is going around at over 1000 mph. So as we all are, in front of the keyboard.

Great, isn't it !
Mind the speed cameras!

Cheers,
Bob

Not sure if its the fastest but the space shuttle in orbit flies at between 17,000 and 18,000 mph or 27,355 to 28,960 km/h.

I don't know the speed - but I think it must have been when the astronauts went to the Moon... assuming they did... because then they would have been out f gravitational and frictional restraints. However, one could rgue that they weren't moving at all - because they were inside the space craft, also doing the same speed.

The speed of light, the same as everything else. This answer is as valid as any other, as you did not provide any context for your question, and I can think of at least 3 sets of valid answers, depending on the context.

The speed needed to get out of the earth's gravitational pull with a rocket...whatever that is.
