By speed · Order from slowest to fastest.

1. An electric scooter 25 km/h

   Shared e-scooters exploded across cities in just a few years, becoming a common sight on sidewalks worldwide.

2. A speeding hovercraft 145 km/h

   A hovercraft floats on a cushion of trapped air, gliding equally well over water, land, ice and mud.

3. A tsunami across the open ocean 800 km/h

   In deep water a tsunami is barely a ripple, racing as fast as a jet before rearing up near the shore.

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 .220 Swift rifle bullet 4.4K km/h

   Among the fastest commercial rifle rounds, it leaves the barrel so quickly the bullet can melt slightly in flight.

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

   The X-15 flew to the edge of space, and several of its pilots earned astronaut wings without leaving a runway.
