Hey kids, I am a black box of an airplane flying from continent to continent. My duty is to record the flight route meticulously from the start of the flight to the end.
I also record the conversation of pilots and their communication with the ground people. Why I am doing this? If any accident happens, this information will come handy for the investigation people. This information is useful to take precautions in the future. I am heavy and could with stand any type of impact.
