I want to know the answer to the following question:
In what year was the advent of heavier-than-air fixed-wing aircraft?
All the background I'm provided with is that "The 1903 advent of heavier-than-air fixed-wing aircraft was closely followed in 1910 by the first experimental take-off of an airplane, made from the deck of a United States Navy vessel (cruiser USS Birmingham), and the first experimental landings were conducted in 1911.". Is that enough to answer the question?
