1928 International Civil Aeronautics Conference
2¢ Wright Brothers Airplane

This stamp was issued in conjunction with the International Civil Aeronautics Conference held at Washington, D.C. The design shows the aircraft used by the Wright Brothers in the first successful flight of heavier than air, powered aircraft. The 1903 flight lasted exactly 12 seconds and covered a distance of 120 feet. The stamp commemorates the 25th anniversary of this first manned flight. Because the Civil Aeronautics stamps pictured airplanes, postmasters often confused them for airmail stamps, marking countless letters “postage due.”
The International Civil Aeronautics Conference stamps were voted #93 in the 100 Greatest American Stamps book.
Civil Aeronautics Conference
The 1928 Civil Aeronautics Conference was likely first suggested by President Calvin Coolidge. One of the most anticipated guests was Orville Wright, as the conference was held just a few days before the 25th anniversary of their first manned flight. Another aeronautic hero, Charles Lindbergh, also attended the event. The conference also hosted 200 representatives from 50 countries who participated in “meetings, conferences, lectures, discussions, and a general exchange of aeronautic ideas [as well as] official and unofficial dinners, banquets, entertainments and sightseeing tours.”
Orville and Wilbur Wright
Sons of a minister in the United Brethren Church, Wilbur Wright (1867-1912) and Orville Wright (1871-1948) grew up to become aviation pioneers. The brothers had always been interested in science and technology, but when their father gave them a flying toy in 1878, they set their sights on developing a heavier-than-air flying machine capable of carrying a man.
Beginning in 1899, the Wright brothers initially experimented with gliders. Within four years, they had built their first airplane. With a wingspan of 40 feet and a 152-pound, 12-horsepower engine, this plane was unlike anything seen before.
The first historic powered airplane flight took place in Kitty Hawk, North Carolina, on December 17, 1903. Orville flew for 12 seconds and traveled 120 feet. Later that day, Wilbur flew for 59 seconds and covered 852 feet.
By modern standards, the Flyer was not impressive. Its double-tiered wings and frame were made of balsa, plywood, and fabric, wired together for rigidity. A 12-horsepower petrol engine, strapped to the platform beneath the wings, catapulted the contraption down a wooden monorail to become airborne. The pilot lay beside the engine and held on. The craft was primitive and unstable. It had no seats, no wheels, and no flaps to control lateral movement. Nonetheless, an engine had powered it into the air.
Using a methodical scientific approach, the Wrights tackled these problems. Eventually they were able to improve stability and control, add seats and wheels, and most importantly, they could design more powerful engines. With each improvement, their aircraft set world speed, height, and distance records.
Despite the Wright brothers’ successful demonstration of powered flight, their innovation remained largely unknown for five years. In 1904 they made a total of 104 flights, but spent only about 45 minutes in the air. However, on October 5, 1905, their machine flew 24.2 miles, remaining airborne for 38 minutes and 3 seconds. The flight was only cut short by the airplane running out of fuel. In 1906, they received a patent for the first airplane.
When the Wrights approached the US military about their invention, they were met with skepticism. The brothers were relatively unheard of, and the military had just spent 50,000 dollars attempting to create a flying machine, only to fail. It was not until 1908 that the brothers received a contract from the military. The Wrights then performed a series of tests and demonstrations at Kitty Hawk, which received heavy coverage from newspapers. After those trials, Wilbur went to France and made many successful demonstrations of their invention. Soon, the entire world knew about their wondrous airplane.
