By speed · Order from slowest to fastest.

1. A chicken foraging 3.6 km/h

   Chickens can recognise over a hundred individual faces, both other birds and the humans who feed them.

2. A fast cricket delivery 161 km/h

   The fastest bowlers can make the ball rise off the pitch toward a batter's head in a fraction of a second.

3. A car cruising the German autobahn 200 km/h

   Parts of Germany's autobahn have no speed limit, where ordinary sedans legally travel faster than racetracks allow elsewhere.

4. A top-fuel dragster 540 km/h

   A dragster covers a quarter mile in under four seconds, accelerating harder than a fighter jet off a carrier.

5. A Boeing 747 cruising 920 km/h

   The 747's hump exists because the cockpit was put on an upper deck so the nose could hinge open for cargo.

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.
