> and often the lives of the innocent who trusted them as well. This is the most crucial part. Maybe you, personally, are OK with modifying your plane and you accept the possibility that your tinkering may cause the plane to crash. But unless you're flying in the middle of Siberia, there are others. The people in the house you may crash in, the people in the other plane you may have just clipped in the runway, the SAR crew that may drown trying to rescue you after your corrupted GPS database diverted the plane to open ocean in stormy IFR conditions. Please everyone, think of their lives even if you're open to risk yours.
