The Barr Brothers is a band founded in Montreal, Quebec, consisting of two American brothers Andrew and Brad Barr and Canadian Sarah Page.
The Green brothers, John (born August 24, 1977) and Hank (born May 5, 1980), are two American brothers, entrepreneurs, social activists, and YouTube vloggers.
 The two extensively work with each other in their lives and careers, having started their collaborative popularity with their "Brotherhood 2.0" project in 2007.
 The Greens' portfolio of online work, which Hank describes as "a small YouTube network with about 15 channels," includes their main "Vlogbrothers" channel, "SciShow", and "The Lizzie Bennet Diaries", among several others.
The Ranger Engines Division (also Ranger Aircraft Engine Division) of the Fairchild Engine & Aircraft Corporation was an American aircraft engine company.
 It was known as the Fairchild Engine Division after World War II.
The Jumo 211 was an inverted V-12 aircraft engine, Junkers Motoren's primary aircraft engine of World War II.
 It was the direct competitor to the famous Daimler-Benz DB 601 and closely paralleled its development.
 While the Daimler-Benz engine was mostly used in single-engined and twin-engined fighters, the Jumo engine was primarily used in bombers such as Junkers' own Ju 87 and Ju 88, and Heinkel's H-series examples of the Heinkel He 111 medium bomber.
 It was the most-produced German aero engine of the war, with almost 70,000 examples completed.
The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American brothers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane.
 They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south of Kitty Hawk, North Carolina.
 In 1904–05 the brothers developed their flying machine into the first practical fixed-wing aircraft.
 Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.
The Curtiss OX-5 was an early V-8 American liquid-cooled aircraft engine built by Curtiss.
 It was the first American-designed aircraft engine to enter mass production, although it was considered obsolete when it did so in 1917.
 It nevertheless found widespread use on a number of aircraft, perhaps the most famous being the JN-4 "Jenny".
 Some 12,600 units were built through early 1919.
 The wide availability of the engine in the surplus market made it common until the 1930s, although it was considered unreliable for most of its service life.
 Today, the engine can be found powering many Edwardian automobile racing specials on the historic racing scene.
Hexatron Engineering Co., Inc. is an American aerospace engineering, aircraft engine and aircraft parts manufacturer based in Salt Lake City, Utah.
 The company was founded in 1982 by Cy Williams and specializes in the design and manufacture of airline aircraft crew seats and also has an aircraft engine design in production for homebuilt, ultralight aircraft and the American light-sport aircraft categories.
Homer Lusk Collyer (November 6, 1881 – March 21, 1947) and Langley Wakeman Collyer (October 3, 1885 – c. March 9, 1947), known as the Collyer brothers, were two American brothers who became infamous for their bizarre natures and compulsive hoarding.
 For decades, the two lived in seclusion in their Harlem brownstone at 2078 Fifth Avenue (at the corner of 128th Street) where they obsessively collected books, furniture, musical instruments, and myriad other items, with booby traps set up in corridors and doorways to ensnare intruders.
 In March 1947, both were found dead in their home surrounded by over 140 tons of collected items that they had amassed over several decades.
The Taylor J-2 Cub (later also known as the Piper J-2 Cub) is an American two-seat light aircraft that was designed and built by the Taylor Aircraft Company.
 The company became the Piper Aircraft Company and the J-2 was first of a long line of related Piper Cub designs.
Charles Edward Taylor (May 24, 1868 – January 30, 1956) was an American inventor, mechanic and machinist.
 He built the first aircraft engine used by the Wright brothers and was a vital contributor of mechanical skills in the building and maintaining of early Wright engines and airplanes.
