How Crucial clues to Air Tragedies can be Found in Black Boxes: The American Airlines jet Crash

Investigators have found the so-called black boxes from an American Airlines Bombardier CRJ-700 regional plane that killed 67 people Wednesday when it plunged into the Potomac River after colliding with a US Army UH-60 Black Hawk helicopter.

According to lead investigator Brice Banning, the helicopter also had “some form of recording devices” that, by current agreements, the Defence Department or the National Transportation Safety Board would read. In reality, they are high-visibility orange rather than black. Although experts cannot agree on the origin of the nickname, it has come to represent the search for solutions after planes crash.

Many historians believe that Australian physicist David Warren invented them in the 1950s. The earliest devices used foil or wire to record a little amount of data. Magnetic tape was used in later gadgets. These days, they use computer chips housed in hard cases. Two recorders are a separate Flight Data Recorder (FDR) and a Cockpit Voice Recorder (CVR) for pilot voices or cockpit noises.

They are required on civil flights and are not intended to establish guilt or liability; rather, their purpose is to retain hints from cockpit data and sounds to assist prevent future mishaps. Some gadgets do both.
