>>The clocks in your house are not as accurate as clocks used for global positioning, which can locate a plane to within +/- 2 inches based on the amount of time it takes for a radiofrequency wave to travel from a GPS satellite to the GPS receiver on board the aircraft.<<

GPS is not linked to the in-flight recorders.

Oh, and BTW, the 2-3" accuracy, we wish! That would make JDAM and other weapon systems a heck of a lot more accurate than they already are.

So your telling me the clocks on aircraft are no more accurate than the clocks in your house? Is that what you are telling me?
