Apollo 10 speed was temporary, or it would have travelled to the moon in 10 hours not 3 days, good comparison though.
They left many off of this Sadly… Like the latest Pluto probe…
+Brent Burzycki and voyager 1
+Brent Burzycki – that's because this chart is of manned flights , I believe (except the bird… I guess it's more of a "highest speed of living things")
+Curtis Boyle That's what I was thinking also. What about the Nasa X-43A, was that piloted?
So technically the fastest manned flight without leaving earth's atmosphere, that we know of, is the X-15 rocket plane?
X43 was unmanned – so I think you are correct – +John Rambo – well as far as we know. I have heard reports the SR71 was faster than what is officially listed – but its not as fast as the X-15. But I assume there is a new scramjet powered craft of some kind – that said the weakest link in going fast – fast is the human in the cockpit…
