The 1911 Curtiss Model D (or frequently, "Curtiss Pusher") was an early United States pusher aircraft with the engine and propeller behind the pilot's seat. It was among the very first aircraft in the world to be built in any quantity — all of which were produced by Curtiss during an era of trial-and-error development and equally important parallel technical development in internal combustion engine technologies.
It was also the aircraft type which made the first takeoff from the deck of a ship (flown by Eugene B. Ely off the deck of USS Birmingham on November 14, 1910, near Hampton Roads, Virginia) and made the first landing aboard a ship (USS Pennsylvania) on January 18, 1911, near San Francisco, California.
It was originally fitted with a foreplane for pitch control, but this was dispensed with when it was accidentally discovered to be unnecessary. The new version without the foreplane was known as the Headless Pusher. Like all Curtiss designs, the aircraft used ailerons instead, which first existed on a Curtiss-designed airframe as quadruple "wing-tip" ailerons on the 1908 June Bug to control rolling in flight, thus avoiding use of the Wright brothers' patented wing warping technology.
The Model D was a biplane fitted with a wheeled tricycle undercarriage. The construction was primarily of spruce, with ash used in parts of the engine bearers and undercarriage beams, with doped linen stretched over it. The outrigger beams were made of bamboo. Prevented by patents from using the Wright Brothers' wing warping technique to provide lateral control, and with neither the Wrights nor himself likely to have known about its prior patenting in 1868 England, Curtiss did not use the June Bug's "wing-tip" aileron configuration, but instead used between-the-wing-panels "inter-plane" ailerons, instead, as directly derived from his earlier Curtiss No. 1 and Curtiss No. 2 pushers. In the end, this proved to be a superior solution. Both the interplane and trailing-edge ailerons on these early aircraft did not use a hand or foot-operated mechanism to operate them, but very much like the earlier Santos-Dumont 14-bis had adopted in November 1906, required the pilot to "lean-into" the turn to operate the ailerons — on the Curtiss pushers, a transverse-rocking, metal framework "shoulder cradle", hinged longitudinally on either side of the pilot's seat, achieved the connection between the pilot and aileron control cabling. Almost all Model Ds were constructed with a pusher configuration, with the propeller behind the pilot. Because of this configuration, they were often referred to as the "Curtiss Pusher". Early examples were built in a canard configuration, with elevators mounted on struts at the front of the aircraft in addition to a horizontal stabilizer at the rear. Later, the elevators were incorporated into the tail unit, and the canard surface arrangement dispensed with, resulting in what became called the Curtiss "Headless" Pushers.
In addition to amateur aviators, a Model D was purchased in April 1911 by the Aeronautical Division of the U.S. Army Signal Corps as a trainer (S.C. No. 2), and by the Navy as an airborne observation platform. A number of them were exported to foreign militaries, as well, including the Russian Navy. On November 14, 1910, Eugene Ely took off from USS Birmingham in a Model D. This was the first time an aircraft had taken off from a ship. On January 18, 1911, Ely landed a Model D aboard USS Pennsylvania. This was the first aircraft to land on a ship.
Upon his election in November 1915, Congressman Orrin Dubbs Bleakley became the first government official to fly from his home state to Washington, D.C. The trip was made in a 75 hp (56 kW) Curtiss biplane from Philadelphia, piloted by Sergeant William C. Ocker, on leave from the United States Aviation Corps at the time. The trip took 3 hours, 15 minutes, including an unscheduled stop in a wheat field in Maryland.

A number of Curtiss Pusher original and reproduction aircraft exist, and reproductions of the design date as far back to the era when the original aircraft was in production, mostly built by private parties.
- Original – Model D in storage with the Ohio History Connection in Columbus, Ohio. It was assembled by Paul and Josh Wilber in Norwalk, Ohio from 1911-1912 and first flew on October 7, 1912. The original Roberts four-cylinder, two-cycle, 50 horsepower engine was replaced by a Kirkham six-cylinder, four-cycle, 50 horsepower engine. The aircraft is currently in storage. Approximately ninety percent of the aircraft is original.
- Replica – Model D airworthy at the Military Aviation Museum in Virginia Beach, Virginia.
- Replica – Model D airworthy at the Old Rhinebeck Aerodrome in Red Hook, New York. It was built for the collection in 1976, and has been powered by first a Hall-Scott V8 engine, and more recently, with a vintage Curtiss V8 engine.
- Replica – Model D airworthy at the Owls Head Maine Transportation Museum in Owls Head, Maine. It has a Continental O-300 engine installed.
- Unknown – Model D airworthy at the Western Antique Aeroplane & Automobile Museum in Hood River, Oregon. It has a Curtiss OX-5 engine installed. It was rebuilt in 1934, but includes parts dating back to 1910.
- Replica – Model D on display at the Western Antique Aeroplane & Automobile Museum in Hood River, Oregon. It has a Continental A-85 engine installed.
- Replica – Model D on static display at the National Air and Space Museum in Washington, D.C. It was built in 1919 and includes parts from an original airframe. It initially had an OX-5 engine installed, but this was replaced by a Curtiss V8. It was donated to the Smithsonian in 1925.
- Replica – Model D on static display at the Minneapolis-Saint Paul International Airport in Saint Paul, Minnesota. It was built in 1964 and was previously owned by Chuck Doyle.
- Replica – Model D on static display at the National Museum of the United States Air Force in Dayton, Ohio. It was completed in 1987 and has a replica engine made of wood and plastic.
- Replica – Model D on static display at the College Park Aviation Museum in College Park, Maryland. It was completed in 2010.

In popular culture
A Headless Curtiss D was the aircraft used by Professor Fate (Jack Lemmon) as the pickup aircraft for a Skyhook-type lift in the prologue section of The Great Race. Fate's assistant, Maximilian Meen (Peter Falk) piloted the D and successfully made the pickup, but was unable to gain altitude and pancaked into a nearby pigpen.

The Aerodrome's Curtiss Pusher was built in 1976 and is powered by an original 1911, 80 HP Hall-Scott engine (since replaced with a restored Curtiss OX-5 engine) obtained from the Smithsonian Institution. It utilizes the original Curtiss control system. The shoulder yoke controls the ailerons as the pilot leans from side to side.
