This is a list of aviation-related events from 1911:

Earle Lewis Ovington was an American aeronautical engineer, aviator and inventor, and served as a lab assistant to Thomas Edison. Ovington piloted the first official airmail flight in the United States in a Blériot XI on September 23, 1911. He carried a sack of mail from Nassau Boulevard aerodrome, Garden City, New York, to Mineola, New York. He circled at 500 feet and tossed the bag over the side of the cockpit and the sack burst on impact, scattering letters and postcards. He delivered 640 letters and 1,280 postcards, including a letter to himself from the United States Post Office Department designating him as "Official Air Mail Pilot #1."
