An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot onboard. Its flight is either controlled autonomously by computers in the vehicle, or under the remote control of a navigator, or pilot (in military UAVs called a Combat Systems Officer on UCAVs) on the ground or in another vehicle.

There are a wide variety of drone shapes, sizes, configurations, and characteristics. Historically, UAVs were simple remotely piloted aircraft, but autonomous control is increasingly being employed.

Their largest use is within military applications. UAVs are also used in a small but growing number of civil applications, such as firefighting or nonmilitary security work, such as surveillance of pipelines. UAVs are often preferred for missions that are too "dull, dirty, or dangerous" for manned aircraft.

The earliest attempt at a powered unmanned aerial vehicle was A. M. Low's "Aerial Target" of 1916.Nikola Tesla described a fleet of unmanned aerial combat vehicles in 1915. A number of remote-controlled airplane advances followed, including the Hewitt-Sperry Automatic Airplane, during and after World War I, including the first scale RPV (Remote Piloted Vehicle), developed by the film star and model airplane enthusiast Reginald Denny in 1935. More were made in the technology rush during World War II; these were used both to train antiaircraft gunners and to fly attack missions. Jet engines were applied after World War II, in such types as the Teledyne Ryan Firebee I of 1951, while companies like Beechcraft also got in the game with their Model 1001 for the United States Navy in 1955. Nevertheless, they were little more than remote-controlled airplanes until the Vietnam Era.

Tim Lucas (born May 30, 1956) is a film critic, biographer, novelist, screenwriter, blogger, and publisher/editor of the video review magazine Video Watchdog.

Lucas, born in Cincinnati, Ohio, was the only child of Marion Frank Lucas, a typesetter and musician, and the former Juanita Grace Wilson; his father died six months prior to his birth, on November 14, 1955, of a congenital heart ailment at age 33. He subsequently spent most of his childhood in the homes of various relatives and caregivers, seeing his widowed mother only on weekends, when she took him to drive-in theaters. After publishing single issues of two fanzines, he became a film critic and cartoonist for Norwood High School's newspaper The Mirror while still a freshman. He began writing professionally at the age of fifteen, when his first reviews were accepted by the influential fantasy film review Cinefantastique. He served at one of the magazine's midwestern bureaus for the next ten years.

Though Lucas never formally graduated high school, he succeeded in placing an essay in Purdue University's literary quarterly Modern Fiction Studies on the occasion of its Autumn 1981 issue, dedicated to British novelist Anthony Burgess. Jokingly, Lucas has described this accomplishment as his "honorary doctorate" because his letter of acceptance was addressed to "Dr. Timothy Lucas." His article, The Old Shelley Game: Prometheus and Predestination in Burgess's Works, was subsequently anthologized in Modern Critical Views: Anthony Burgess (1987, ISBN 0-87754-676-2), a collection "of the best criticism available upon the novels of Anthony Burgess" in the words of its editor, Harold Bloom.
