Test of relativistic time dilation

The Hafele–Keating experiment was a test of the theory of relativity.
In 1971, Joseph C.
Hafele, a physicist, and Richard E.
Keating, an astronomer, took four caesium-beam atomic clocks aboard commercial airliners.
They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory.
When reunited, the three sets of clocks were found to disagree with one another, and their differences were consistent with the predictions of special and general relativity.
