An experiment using civilian aircraft and atomic clocks to provide evidence for Einsteins time dilation theory. Time dilation applies to satellites that orbit the earth as they move forward in time by 0.01 seconds per year. This may not seem much but the clocks on the satellites need to take this into account in order to stay in time with clocks on earth.
