What is the orgin of the name black box even though it is not black?

Answer 1

The color black is often connected to death. When you attend funerals you wear black, hearses are black etc.

The black-box is there to tell the story of the now-dead flight crew. Although it isn't always the case that everyone onboard died, the black-box was designed for these situations, and the name just stuck. ==Another possibility... The term "black box" also refers to a stand-alone electronic unit that is removable and replaceable in its entirety without having to cut and splice wires. Black boxes in aviation refer to the Cockpit Voice Recorder (CVR) and the Digital Flight Data Recorder (DFDR) which are stand alone units that are removable for study simply by sliding out of their racks. In these days, however, data from black boxes is usually downloaded by computer hook-ups.
