    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!

    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.

    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.
