In terms of remaining in sea-level air as opposed to passing through it and attaining max speed in space (such as a satellite), I believe high-velocity artillery shells could be the fastest.

After that, consider the end of a bullwhip. When the whip is cracked, the end of the whip moves at the speed of sound.

The fastest object I'm aware of given your conditions is a 5.56 mm rifle bullet.
