1. A galloping racehorse 88 km/h

   All thoroughbred racehorses descend from just three stallions imported to England centuries ago.

2. A peregrine falcon in a dive 410 km/h

   The peregrine is the fastest animal on Earth, diving so fast it has baffles in its nostrils to breathe.

3. The land-speed record car 1.2K km/h

   ThrustSSC became the first car to break the sound barrier, its twin jet engines kicking up a desert dust storm.

4. The SR-71 Blackbird 3.5K km/h

   The Blackbird leaked fuel on the ground because its panels only sealed once heat expanded them in flight.

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. NASA's X-43 scramjet 11.9K km/h

   The X-43 set an air-breathing speed record by burning fuel in a stream of air rushing through it many times faster than sound.
