“If two wrongs don’t make a right, what do two rights make?"/"An airplane.”

A popular aviation riddle about the Wright Brothers is:

Q: If two wrongs don’t make a right, what do two rights make?
A: An airplane.


The joke has been cited in print since at least 1969.


Wikipedia: Wright Brothers
The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American brothers, inventors, and aviation pioneers who are credited with inventing and building the world’s first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903 four miles south of Kitty Hawk, North Carolina. In 1904-1905 the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.
