The first modern flight recorder, called "Mata Hari", was created in 1942 by Finnish aviation engineer Veijo Hietala.

In 1965 black boxes were redesigned and moved to the rear of airplanes to improve the probability of successful data retrieval after a crash.

In 1953, Australian engineer David Warren conceived a device that would record not only the instruments reading, but also the cockpit voices. He built the first prototype in 1958.

er Uses

Although known as black boxes, in fact they are painted bright orange to the most visible, due to the high contrast on the ground, leaves and water. They also mounted equipment underwater location beacon (ULB).

Each signal device capable of detecting the ultrasonic waves once per second and continuously for 30 days.

Today, the black box is not only used in the aircraft, but also be mounted on the trains and cars.
