It's hard to say. Officially, the fastest jet plane ever built is the SR-71 Blackbird, built by Lockheed. It was capable of speeds in excess of 3.5 mach (more than 2,200 miles per hour). It was decommissioned in 1998.
At 3:21 p.m. (EDT), NASA'S Juno Mission spacecraft will slingshot around Earth towards Jupiter, accelerating to 25 miles per second along the way and becoming the fastest man-made object in history. A .50-caliber bullet travels at about half a mile a second, by contrast -- nowhere near the blistering speed of Juno.
