Is A black box black?

Whenever a plane crash occurs, 

people search for the cause of the crash by baking a look at the "Black box." 

A black box is a flight recorder that records what happened before the crash. 

Although people commonly think that the black box is black, it is actually orange.


 Because the color orange is easy to spot, orange black boxes are easier to find at 

crash scenes. 

So why are flight recorders called "black boxes" when they are not even black? 


It is because the term black box refers not to the exterior of the box, 

but to the interior, which is dark and holds the key to a secret.

 The black box was invented by Australian David Warren.

 David's father died in a plane crash when David was only 9.

 While working as a scientist at the Aeronautical Research Laboratory in Australia, 

David came up with the idea to build a flight recorder.



 Still, David did not give up. 



 In 1957, he built the first flight recorder.

 In 1963, the Australian government finally passed a law requiring all 

 commercial planes to install flight recorders. 

Today, black boxes are installed in almost every plane in the world.
