An air speed record is the highest airspeed attained by an aircraft of a particular class. ... fastest free-flying air-breathing vehicle [73] 22 April 2010: Uncrewed:
This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when flying horizontally. The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives.

It is the fastest mammal in the world and one of the fastest flying animals on level flight. Cheetah: 109.4–120.7 km/h (68.0–75.0 mph) [d] The cheetah can accelerate from 0 to 96.6 km/h (60.0 mph) in under three seconds, [58] though endurance is limited: most cheetahs run for only 60 seconds at a time.

On January 19, 1937, a year and a half after setting the landplane speed record in the H-1, Hughes broke his own transcontinental speed record by flying non-stop from Los Angeles to New York City in 7 hours, 28 minutes and 25 seconds, smashing the previous time of 9 hours, 27 minutes by two hours. His average speed over the flight was 322 mph ...
For comparison, the record holder for a land-based aircraft was held (for a time) by the Hughes H-1 Racer with a top speed of only 566 km/h (352 mph). Then, in 1939, two German racing aircraft surpassed the M.C. 72. The first was a Heinkel prototype fighter which reached the speed of 746 km/h (464 mph
Riding a motorcycle off the edge of a cliff is not the only death-defying stunt Tom Cruise pulls off in the upcoming “Mission: Impossible – Dead Reckoning Part One.” A new featurette on the ...
Fabric-covered biplanes of the World War I era and shortly after could reach 200 mph (320 km/h). In 1925 U.S. Army Lt. Cyrus K. Bettis flying a Curtiss R3C won the Pulitzer Trophy Race with a speed of 248.9 mph (400.6 km/h). [15] Speeds of all-metal monoplanes of the 1930s jumped to 440.6 mph (709.1 km/h) with the Macchi M.C.72 floatplane. [16]
