Both are stores at the rear of an aircraft. There the fuselage meets the upper tail fin – the part of plans that the best survival record. The same principle applies to human passengers – you’re safer at the back.

Despite their reputation, neither box in fact indestructible. They can withstand a temperature of 1,100 C for 30 minutes and 250 C for 10 hours. They must also be able to survive and impact force of gravity.

Flight recorders are encased in two thickness of platinum. Memory chips holds the flight data. While FDR`s make an electronic record of the plane’s mechanical performance, CVR`s record the communication between the crew. But they are still only recorded in 80 percent of accidents.
