The Apollo flights to the moon. They achieved a velocity of about 25,000 miles per hour--a good bit faster than orbital missions (about 17500). Some unmanned spaceprobes to other planets have gotten to higher velocities, but that's the fastest humans themselves have everr gone. The first to actually do this was Apollo 8 (Borman, Lovell, Anders--Decempber 1968)--so I guess they hold the record.

The Earth travels at about 100,000 MPS(Miles Per Second) but the fastest manmade speed (minus earth's speed) in when military jets or shuttles land (at ~ Mach 27-Mach 75)

The fastest manmade object is the unmanned probe to Pluto, New Horizons. Launched a year ago, it is going to get a gravity assist from Jupiter next month.

Shuttles orbiting the Earth travel at about five miles per second (? something like that). Nothing close to that has been reached within the atmosphere.
