The fastest plane, SR-71 also known as Blackbird flew at Mach 3+ speed. Mach = speed of sound = 768 miles per hour = 0.213 miles per second. So the maximum speed achieved by a man made object is 0.65 miles per second.
You can see we are a very long way away from speed of light = 186,000 miles per second (compared to 0.65 miles per second by SR-71).

But that is within our atmosphere. The New Horizons spacecraft is traveling 34,000 mph in space. The Apollo 10 has the speed record for a manned spacecraft at 24,791 mph.

I think our spacecraft fly a whole lot faster than the SR-71. In fact, I know they do.
The man-made Saturn/Apollo spacecraft achieved 25,000 MPH, in trans lunar injection or nearly 7 miles/second. That is the fastest man has ever traveled.
Many of the unmanned deep-space probes have reached far higher speeds.
