Today is National Aviation Day and for the country’s jet-setters that is reason to celebrate. The holiday coincides with the birthday of Orville Wright who, together with his brother Wilbur, designed the first powered airplane. President Franklin Roosevelt first proclaimed Aug. 19 National Aviation Day back in 1939 and we are still celebrating it now.

In honor of the Wright brothers and all those who have contributed to powered flight, we have come up with a list of some essential developments since the first airplane puttered 20 feet above a wind-swept beach in North Carolina. Here you have it, some of the most momentous advances in modern air travel.
