B-24 Liberator in the context of "Ceiling (aeronautics)"

Manufacturing engineering or production engineering is a branch of professional engineering that shares many common concepts and ideas with other fields of engineering such as mechanical, chemical, electrical, and industrial engineering. Manufacturing engineering requires the ability to plan the practices of manufacturing; to research and to develop tools, processes, machines, and equipment; and to integrate the facilities and systems for producing quality products with the optimum expenditure of capital.

The manufacturing or production engineer's primary focus is to turn raw material into an updated or new product in the most effective, efficient & economic way possible. An example would be a company uses computer integrated technology in order for them to produce their product so that it is faster and uses less human labor.

The Consolidated Aircraft Corporation was founded in 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors. Consolidated became famous during the 1920s and 1930s for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies. Equally famous was the B-24 Liberator, a heavy bomber which, like the Catalina, saw action in both the Pacific and European theaters.

In 1943, Consolidated merged with Vultee Aircraft to form Consolidated-Vultee Aircraft, later known as Convair. The Los Angeles-based Consolidated Steel Corporation is not related.

A twin tail is a type of vertical stabilizer arrangement found on the empennage of some aircraft. Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer. This arrangement is also known as an H-tail, as it resembles a capital "H" when viewed from the rear. The twin tail was used on a wide variety of World War II multi-engine designs that saw mass production, especially on the American B-24 Liberator and B-25 Mitchell bombers, the British Avro Lancaster and Handley Page Halifax heavy bombers, and the Soviet Union's Petlyakov Pe-2 attack bomber.

It can be easily confused for the similarly named twin-boom (or "double tail") arrangement, which has two separate tail-booms from the same fuselage rather than a single tail with twin stabilizers (a singular "twin tail" vs. two identical tails).

George Stanley McGovern (July 19, 1922 – October 21, 2012) was an American politician, diplomat, and historian from South Dakota who served in both chambers of the United States Congress as a member of the United States House of Representatives for two terms representing South Dakota's 1st congressional district from 1957 to 1961, the director of Food for Peace in 1961 and 1962 under John F. Kennedy, and a member of the United States Senate for three terms from 1963 to 1981, and was the Democratic Party presidential nominee in the 1972 U.S. presidential election.

Born in Avon, South Dakota, McGovern grew up in Mitchell, South Dakota, where he became a renowned debater. He volunteered for the U.S. Army Air Forces upon the country's entry into World War II. As a B-24 Liberator pilot, he flew 35 missions over German-occupied Europe from a base in Italy. Among the medals he received was a Distinguished Flying Cross for making a hazardous emergency landing of his damaged plane and saving his crew. After the war, he earned degrees from Dakota Wesleyan University and Northwestern University, culminating in a PhD, and served as a history professor. He was elected to the U.S. House of Representatives in 1956 and re-elected in 1958. After a failed bid for the U.S. Senate in 1960, he was a successful candidate in 1962.
