2. A common swift in flight 113 km/h

   Swifts can stay airborne for nearly a year without landing, even sleeping on the wing high above the ground.

   Luge athletes steer a tiny sled with subtle leg and shoulder pressure while lying on their backs, feet first.

4. A golf ball off the driver 340 km/h

   A driven golf ball can briefly spin thousands of times a minute, which is what makes it climb and hold the air.

5. The core of a jet stream 442 km/h

   Pilots ride these high-altitude winds to save fuel, which is why eastbound flights are often much quicker.

6. A bullet from an AK-47 2.7K km/h
