In 1953, Dr David Warren who was working with the "Defence Science and Technology Organisation" Aeronautical Research Laboratory in Melbourne, Victoria, Australia) was widely credited with creating the prototype of the "The Black Box Flight Recorder” an advance in aviation that was partly inspired by the death of his father in a plane crash when he was 8.
“The Black Box Flight Recorder” is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of an aircraft accident. For this reason, “The Black Box Flight Recorder” are required to be capable of surviving the conditions likely to be encountered in a severe aircraft accident.
“The Black Box Flight Recorder” can withstand temperatures of up to 1100 degree Celsius, submersion in water for 30 days, pressure of 5000 pounds per square inch & a force of 3400 times its own weight.
It's prominently colored bright orange or yellow with reflective surfaces to facilitate recovery of "The Black Box Flight Recorder" from an aircraft accident site.
