Hello guys, I'm back with my another exciting blog. You might be thinking that 'Black Box' as the name suggests must be Black in colour but that's not the fact. First of all, officially it is not called as a 'Black Box'. The proper name of what we know as the ‘black box’ is Flight Data Recorder (FDR). And that is exactly what is does; it records flight data such as engine exhaust, temperature, fuel flow, aircraft velocity, altitude and rate of descent electronically in order to facilitate investigations after an accident. And to be honest, calling it a recorder is more realistic than calling it a box. Secondly, It's not black but bright orange in colour. The black box is made of fire resistant material which is bright orange. It is not 100% clear why it is called ‘black box’ and not ‘orange box’, but there are some theories. It may be because it is often charred black after a crash, it may be because the very first boxes were painted black to prevent reflection or because ‘black box’ is a general name in science for devices with in- and output of data with complex internal workings. I used to think it was because a Mr. Black invented it, but that is not true. David Warren, an Australian scientist, invented the black box in 1957.
