Please answer this: Information:  - A military aircraft is any fixed-wing or rotary-wing aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat:  - Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people (communications intelligenceabbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligenceabbreviated to ELINT). Signals intelligence is a subset of intelligence collection management.  - Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word "aviation" was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb "avier" (synonymous flying), itself derived from the Latin word "avis" ("bird") and the suffix "-ation".  - The Wright Flyer (often retrospectively referred to as Flyer I or 1903 Flyer) was the first successful heavier-than-air powered aircraft. It was designed and built by the Wright brothers. They flew it four times on December 17, 1903, near Kill Devil Hills, about four miles south of Kitty Hawk, North Carolina, US. Today, the airplane is exhibited in the National Air and Space Museum in Washington D.C.  - Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. This role can fulfil a variety of requirements, including the collection of imagery intelligence, observation of enemy maneuvers and artillery spotting.  - Imagery intelligence (IMINT) is an intelligence gathering discipline which collects information via satellite and aerial photography. As a means of collecting intelligence, IMINT is a subset of intelligence collection management, which, in turn, is a subset of intelligence cycle management. IMINT is especially complemented by non-imaging MASINT electro-optical and radar sensors.  - Measurement and signature intelligence (MASINT) is a technical branch of intelligence gathering, which serves to detect, track, identify or describe the signatures (distinctive characteristics) of fixed or dynamic target sources. This often includes radar intelligence, acoustic intelligence, nuclear intelligence, and chemical and biological intelligence. MASINT is defined as scientific and technical intelligence derived from the analysis of data obtained from sensing instruments for the purpose of identifying any distinctive features associated with the source, emitter or sender, to facilitate the latters measurement and identification.  - A reconnaissance aircraft is a manned or unmanned military aircraft designed, or adapted, to carry out aerial reconnaissance. Their roles are to collect imagery intelligence, signals intelligence, and measurement and signature intelligence.  - The AEG C.IV was a German two - seat biplane reconnaissance aircraft that entered service in 1916 . The C.IV was based on the AEG C.II , but featured a larger wingspan and an additional forward - firing Spandau - type 7.92 mm ( .312 in ) machine gun . In addition to reconnaissance duties , the C.IV was used as a bomber escort , despite proving itself inadequately powered for the role . Nevertheless , the C.IV was easily the most successful of AEG 's World War I B - and C - type reconnaissance aircraft , with some 400 being built and the model remained in service right up to the end of the war . A variant , the C.IV.N was designed specifically as a prototype night bomber in 1917 , with the Benz Bz.III engine used in other C - types and a lengthened wingspan . Another variant , the C.IVa , was powered by a 130 kW ( 180 hp ) Argus As III engine . C.IV aircraft saw service with the Bulgarian Air Force and the Turkish Flying Corps .  - A fixed-wing aircraft is an aircraft, such as an aeroplane, which is capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, in which the wings form a rotor mounted on a spinning shaft, and ornithopters, in which the wings flap in similar manner to a bird.  - A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s.

Please answer this: Information:  - The IND Eighth Avenue Line is a rapid transit line in New York City, United States, and is part of the B Division of the New York City Subway. Opened in 1932, it was the first line of the Independent Subway System (IND), and the "Eighth Avenue Subway" name was also applied by New Yorkers to the entire IND system. Most of the line has four tracks, with one local and one express track in each direction, except for the extreme north and south ends, where only the two express tracks continue. The line is signaled as Line "A", with tracks A1, A3, A4, and A2 from west to east, running from approximately 800 at the south end to 1540 at the north end (measured in feet).  - The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.  - Rector Street was a station on the demolished IRT Ninth Avenue Line . It had two tracks and two side platforms , though two additional tracks ended at a bumper just south of the station . It was served by trains from the IRT Ninth Avenue Line . It closed on June 11 , 1940 . The next southbound stop was Battery Place . The next northbound stop was Cortlandt Street for Ninth Avenue Line trains .  - An elevated railway (also known as El rail or simply El for short, and, in Europe, as overhead railway) is a rapid transit railway with the tracks above street level on a viaduct or other elevated structure (usually constructed of steel, concrete, or brick). The railway may be standard gauge, narrow gauge, light rail, monorail, or a suspension railway. Elevated railways are usually used in urban areas where there would otherwise be a large number of level crossings. Most of the time, the tracks of elevated railways that run on steel viaducts can be seen from street level.  - The IRT Ninth Avenue Line, often called the Ninth Avenue El, was the first elevated railway in New York City. It opened on July 1, 1868 as the West Side and Yonkers Patent Railway, as an experimental single-track cable-powered elevated railway from Battery Place, at the south end of Manhattan Island, northward up Greenwich Street to Cortlandt Street. It ceased operation on June 11, 1940, after it was replaced by the IND Eighth Avenue Line which had opened in 1932.
