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

   Streamlined record bikes look like rockets on wheels, with the rider lying flat inside a sealed shell.

   Sound travels faster in warm air than cold, so a thunderclap's timing shifts slightly with the weather.

5. A fired shotgun slug 1.9K km/h

   A shotgun slug is a single heavy projectile that turns a scattergun into a short-range, hard-hitting rifle.
