Recorder Red
why is a flight black box recorder red not black?
Actually, they are called “black box” only because this is the term used to identify a device where the inner working principle is not of paramount importance. It does not matter how flight data recorder operate: it could be magnetic tape, a hard disk, solid state chips; all that matter is that it records data. In the early days, there even were recorders that scored a groove on a ductile metallic strip; I have no idea how many cycles it could go through before the ribbon was worn.
Anyway, as others have noted, they are painted bright orange so as to make them easier to spot.
