Help answer this question below.
Without a doubt interms of air-breathing jet engined planes it is the SR-71 "Blackbird".
While techincally not a plane, its interesting to note that a NASA Space Shuttle (which obviously looks like a plane) is capable of speeds of 20,000km/h while in orbit without using its solid rocket engines!
Fastest plane with air breathing engines: SR-71 Blackbird.
Officially... the SR-71 Blackbird is the fastest production aircraft ever made, with a top speed so fast... it's classified.
Unfortunately this aircraft is no longer in use by the U.S. Military (there are a couple still being used by NASA), which begs the question... "If they don't have the SR-71 anymore, what did they replace it with?"
There's a chance that the US has a new "skunkworks" aircraft that replaced the Blackbird that is so fast, that if they told you about it they'd have to kill you.
Hope this helps.
the one you haven't heard about,
I've seen it,

if you thinking about fastest commercial aircraft currently in service, it's B747 (but due to improve fuel economy current airliners operate below it's max operating speed).
The fastest civilian aircraft currently in use is the Cessna Citation X, with a cruise speed of Mach 0.92.
Only including air-breathing planes, the X-7 at 2,881 mph (the SR-71 went 2,242 mph). If you include rocket powered planes it's the X-15, which went 4,519 mph.
Pictures: (1) X-7. (2) X-15

correct, I even had the opportunity see this fine aircraft on a daily basis, over at Kadena airvase in Okinawa, when I served with the USMC.

I absoulutely love the SR-71 "Blackbird" its was such an extreme plane!
Although I have not personlly saw a real one for myself (I live in Australia) I am glad to report that this plane might be making an apperance in the Tranformers (2007 film) sequel, Transformers 2: The Revenge of The Fallen.
It has been rumoured that it is the mechanical form of Starfire (Starscream's twin brother).

Well it is a sight to behold, a noise that you will never forget but, don't sneeze because you will miss it.
by deltabtry on October 5th, 2008
to me it seems a like a true marvel, it should be praised as one of man kind's greatest acheivements. hopefully the movie does justice to it.

We all knew before it took off from Kadena AFB, there would be a couple of F-15's circling the air space. When it powered up for take off the whole base used to shake, and we were a few miles away. Once it lifted off it looked like a black pin head with the needle length flame coming from the back. A few short minutes later a sonic boom could be heard. North Korea I believe shot a missle at it back in 1981 and the SR-71 simply out ran the missle by 8 miles.

yeah all i've heard and seen in doco's and articles that the SR-71 was impervious to missile attacks with it's main defences consisting of extreme altitude and absoulute speed
There was a funny comment from an SR-71 engineer that the SR-71 is the reasoning for the "miss" part of the word missile.
I forgot who said that but it's still true to the day!
Ps: what was the average altittude when the SR-71 broke the sound barrier?
by MetalRain on October 5th, 2008
Geeze I have no clue but, from what I have seen and the rate of climb I would venture to guess perhaps 5k to 10k but, I think it had more to do with distance away from a populace area in Okinawa.
by deltabtry on October 5th, 2008
BTW there where two SR-71 stationed at Kadena, when parked it was heavly guarded with lethal force authorized and totally inclosed.
by deltabtry on October 5th, 2008
haha yeah, constant sonicbooms would annoy the populace! what nicknames did you give them birds?
by MetalRain on October 5th, 2008
Blackbird or in the middle of the night when we were waken up by the noise, they would be sixty of us in the squad bay saying many colorful metaphors.

were there defence force issued earmuffs? lol, nice to here this kinda stuff from someone who actually cares about these amazing machines!
by MetalRain on October 5th, 2008
I imagine those on the flight line did but, those of us on camp Butler where not issued any ear muffs besides that would take away all the fun. I served in the USMC and was a artilleryman so not only am I acustomed to load bangs, I enoy it as well. Non the less I have has a love affair with aviation. hre is a favorite link of mine: BTW live fire airshow....
