A flight recorder is generally known as black box. It is an electronic recording device which is placed in an airplane and is used for the investigation of aviation accidents and other incidents. Presently it is available in orange in color.
Dr. David Warren was the first Australian scientist who invented the black box. The Australian scientist was working at the Aeronautical Research Laboratory in Melbourne in the mid-1950s and he was involved for the examination of the mysterious accidents in the world’s first jet-powered commercial aircraft.
