Origin of Term
The term black box was first recorded used by the RAF of approximately 1947 to describe the sealed containment used for apparatus of navigation, this usage becoming more widely applied after 1964. The identifier is therefore applied to objects known as the flight data recorder (FDR) and cockpit voice recorder (CVR). These function to record the radio transmissions occurring within an airplane, and are particularly important to persons who engage into an inquiry into the cause of a plane crashing, where the plane is caused to become wreckage. These boxes are in fact coloured orange in order that they be more easily located.

Famous quotes containing the words origin of, origin and/or term:
“For, though the origin of most of our words is forgotten, each word was at first a stroke of genius, and obtained currency, because for the moment it symbolized the world to the first speaker and to the hearer. The etymologist finds the deadest word to have been once a brilliant picture.”
—Ralph Waldo Emerson (1803–1882)
“Our theism is the purification of the human mind. Man can paint, or make, or think nothing but man. He believes that the great material elements had their origin from his thought.”
—Ralph Waldo Emerson (1803–1882)
“The developments in the North were those loosely embraced in the term modernization and included urbanization, industrialization, and mechanization. While those changes went forward apace, the antebellum South changed comparatively little, clinging to its rural, agricultural, labor-intensive economy and its traditional folk culture.”
—C. Vann Woodward (b. 1908)
