16th March 1926 – First liquid-fueled rocket launched

Robert H. Goddard launched the world’s first liquid-fueled rocket on 16th March 1926.

NASA Fact sheet on Goddard says:

By 1926, Goddard had constructed and tested successfully the first rocket using liquid fuel. Indeed, the flight of Goddard’s rocket on March 16,1926, at Auburn, Massachusetts, was a feat as epochal in history as that of the Wright brothers at Kitty Hawk.

It also lists these firsts:

• First explored mathematically the practicality of using rocket propulsion to reach high altitudes and even the moon (1912);
• First proved, by actual static test, that a rocket will work in a vacuum, that it needs no air to push against;
• First developed and shot a liquid fuel rocket, March 16,1926;
• First shot a scientific payload (barometer and camera) in a rocket flight (1929, Auburn, Massachusetts);
• First used vanes in the rocket motor blast for guidance (1932, New Mexico);
• First developed gyro control apparatus for rocket flight (1932, New Mexico);
• First received U.S. patent in idea of multi-stage rocket (1914);
• First developed pumps suitable for rocket fuels;
• First launched successfully a rocket with a motor pivoted on gimbals under the influence of a gyro mechanism (1937).
