Dayton Aviation Heritage NHP, Dayton, Ohio

The most famous brothers in the 20th century surely are Orville and Wilbur Wright. The NPS has two major units dedicated to their revolution in transportation—one at Kitty Hawk, North Carolina where they first accomplished powered flight and the other at Dayton, Ohio which contains five units across the city. Here’s their story.

Neither Wilbur (1867-1912) nor Orville (1871-1948) earned their high school diplomas, but instead invented from an early age. In 1889, they started a printing business, first as newspaper publishers and then as commercial printers. One of their early clients was Paul Laurence Dunbar, a celebrated African-American poet and writer.

Looking for new business opportunities, in 1892 the brothers opened a repair shop to tap into the growing popularity of bicycles. By 1896, they were building small numbers of their own brand, called the Hercules. Their printing and bicycle businesses allowed them both the time and the machine shop to pursue another interest. Spurred on by news of experiments in flight, Wilbur in 1899 wrote the Smithsonian Institute and asked for any information about aeronautics. More about the Smithsonian later.

They flew kites around Dayton and asked the U.S. Weather Bureau where reliable winds blew. In 1900, Wilbur and Orville took their gliders and camped out at Kitty Hawk on the Outer Banks of North Carolina. From watching birds fly, they developed a concept called Wing Warping that torqued the wings to allow some control over flight. Nonetheless, progress was slow that year and the next and on the train home from the 1901 experiments at Kitty Hawk, Wilbur said to Orville that man would not fly for 1,000 years.

That winter, they built a wind tunnel at their bike shop and conducted over 200 experiments on the shape of wings. They also worked on creating a light weight engine for their plane. They returned to Kitty Hawk in 1902, set up shop in a tent on the wind swept dunes, and completed between 700 and 1,000 flights with their glider that fall. This plane “embodied their core invention, a complete system of flight control…. The 1902 glider represented a stunning breakthrough.” In fact, when they applied for a patent several years later, they submitted the plans for the glider and its controls instead of their powered plane.[1]

The Wrights returned to Kitty Hawk on September 26, 1903. On December 17th, Wilbur and Orville traded off climbing aboard their bi-plane for short powered flights. On his second flight, Wilbur traveled 852 feet and remained airborne for almost a minute of flight. The Wrights had attained the long sought dream of human flight. They returned to Dayton and decided to continue flight experiments closer to home. They had proved that humans could fly. They now needed to create a practical plane that could be controlled in the air.

Winds at Huffman Prairie Field north of Dayton did not blow as hard as at Kitty Hawk. To compensate, in 1904 they built a catapult to fling their planes into the air, much like aircraft carriers use today. The challenge in creating a practical plane entails finding ways to control the three directions that a plane must navigate—pitch or up and down, right and left, and yawl or roll. Small wings called elevators control the pitch, rudders point the plane right or left, and wing warping controls the roll of a plane.

Failures plagued the Wright Brothers, including accidents like the one when Orville lost control and crashed into the field at 30 mph.  Finally, on October 5, 1905, Wilbur took off in a plane of fabric and wood and stayed aloft for almost forty minutes covering twenty-three miles in circles around Huffman field. The brothers then they halted all of their flights since they feared that others would steal their invention and applied for patents to protect their invention. The U.S. granted them a patent in 1906 which lasted until 1923. Others challenged their monopoly as we shall see. The next time the brothers flew (and the first time as a public demonstration) was in France on August 8th, 1908 when they kept their plane up for an hour and forty-five minutes. They became international heroes, feted at home and abroad.

At Huffman Prairie Field on the day I visited, Robert Petersen stood next to a replica of an early Wright Brothers’ plane. A gifted story teller, Robert impressed on the visitors that the day of the importance of this field for the Wrights. It gave them a nearby place to test their models and so was the world’s first air port. The key successes came in 1905. The year before, they had flown 105 flights and were aloft for forty-nine minutes. In 1905, they conducted fifty flights and were in the air for 262 minutes. I asked Robert why Dayton was the right place at the right time for this invention. First, he said that few places in the U.S. had the ability to cast aluminum block engines, but Dayton did. He also stated that Dayton was Invention City—it had more patents per capita than anywhere else in the country. He reeled off some of the inventions that happened here—the electric starter for cars, air conditioning, fast drying paint, the bar code, the step ladder, pop top openers for cans, and the Yellow Pages. The National Cash Register (NCR) not only invented the mechanical cash register in Dayton but it also served as an incubator for people who later created Frigidaire, Delco, IBM, and Lear Jet. Looking out over Huffman Prairie Field, he concluded: “Kitty Hawk was the first powered flight. Here is the rest of the story. There are very few places where you can stand that transformed the world. This is one of those places. I can tell all of world history right here.”

The Wright Brothers’ success lit a fire under aeronautic innovators around the world. Now that the Wrights had proved that human flight was possible, innovations burst into the air like a covey of quail spooked out of a bush. One of the most prolific innovators was motorcycle pioneer Glenn Curtiss. Here are some of his accomplishments on the heels of the Wrights. The most important was that Curtiss put ailerons on his planes which allowed for greater control of the flying machines. Using the ailerons, Curtiss racked up an impressive list of firsts in aviation history:  he flew the first public flight of a plane in the U.S. in 1908; he built the first commercially available airplane in 1909; he flew from Albany to New York City, a long distance record at the time, in 1910; he earned the first pilot’s license in 1911; he built the first plane that took off from water in 1911 and developed the first flying boat in 1912; he invented the first dual pilot control in 1911; he created the first retractable landing gear in 1911; he produced 6,000 Jenny airplanes for the Allies in World War I; and his Curtiss NC-4 was the first plane to fly across the Atlantic with stops in the Azores in 1919. The Glenn Curtiss Museum in Hammondsport, N.Y. celebrates these accomplishments.

So why are there two National Park units dedicated to the Wrights, an Air Force Base named after them, and we all know about Wilbur and Orville but not about Glenn? I asked this to the people at the Curtiss Museum. The best answer came from the crew renovating a P-40, the Warhawk fighter, in a workshop behind the main building. Their theory is that the Wrights had deposited their Kitty Hawk plane on display in London. Samuel Pierpont Langley, the director of the Smithsonian Institution, and an aeronautics pioneer in his own right, wanted to secure the plane for the museum. The deal he brokered with the Wrights was that they would donate their plane but the Smithsonian would not mention the accomplishments of Curtiss. As one staff member said when I asked why the lack of recognition, “It’s political.”

Tom Crouch in his First Flight book covers the controversy. In 1914, the Smithsonian had loaned Director Langley’s unsuccessful plane the Aerodrome to Curtiss who rebuilt and flew it. Then the Smithsonian displayed it as the first machine capable of flight. In 1928, Orville sent their 1903 plane to London’s Science Museum, vowing to keep it there until the Smithsonian acknowledged that the Wright plane was, well the right plane. Finally in 1942, the museum admitted that Langley’s plane was not the first, and the world’s first airplane was unveiled at the Smithsonian on Dec. 17, 1948.[2] Was there an agreement to downplay Curtiss’s innovations? I can’t say.

The Wright Brothers’ had little success in advancing aeronautics after they proved that human flight was possible. They fought with Curtiss and others over infringements on their invention, and some say that Wilbur died in 1919 stressed over these battles. Whatever the subsequent history of aviation, Wilbur and Orville opened the door for human flight and changed our world. Their invention ranks as one of the most revolutionary ones of all time. 

The Wright Brothers National Monument at Kitty Hawk, North Carolina was authorized as Kill Devil Hill Monument March 2, 1923, transferred from the War Department to NPS in 1933, and renamed on December 4, 1953.The Dayton Aviation Heritage National Historical Park was created on Oct. 16, 1992 to preserve the sites in Dayton connected to the Wright Brothers and to honor Paul Laurence Dunbar, a renowned African-American poet and writer who had the Wrights print some of his books.

Next Monday evening, I will post a new blog on Hopewell Culture National Historical Park and the 2,000 year old mounds preserved at that site.
