1. A racing greyhound 76 km/h

   Greyhounds reach their top speed in just a few strides and spend much of a sprint completely airborne.

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

3. A racing bobsled 150 km/h

   Bobsled crews sprint to shove the sled at the start, then leap in, as those first seconds decide the race.

   The Cessna 172 is the most-produced plane in history and the trainer that taught millions of pilots to fly.

5. A tank's sabot round 5.8K km/h

   A sabot round sheds a casing in flight, leaving a slim dart of dense metal that punches through armour.

6. The X-15 rocket plane 7.3K km/h
