Why is the black box orange?
The black box is a more general term for the Flight Data Recorder and the Cockpit Voice recorder of an Aircraft. Coming to your question, these ‘black’ boxes are actually painted with a heat-resistant bright orange colour in order to make them easier to find in the wreckage resulting from the crash.
