1971年10月，四个铯束钟乘坐商业喷气式飞机在世界各地飞行，一次向东，一次向西，记录了与方向有关的时间差，这与传统相对论的预测非常一致。相对于美国海军天文台的原子时标，飞行钟在向东飞行期间损失了59 ± 10纳秒，在向西飞行期间获得了273 ± 7纳秒，其中误差是相应的标准偏差。这些结果提供了一个明确的经验解决著名的时钟“悖论”与宏观时钟。
Four cesium beam clocks flown around the world on commercial jet flights during October 1971, once eastward and once westward, recorded directionally dependent time differences which are in good agreement with predictions of conventional relativity theory. Relative to the atomic time scale of the U.S. Naval Observatory, the flying clocks lost 59 ± 10 nanoseconds during the eastward trip and gained 273 ± 7 nanoseconds during the westward trip, where the errors are the corresponding standard deviations. These results provide an unambiguous empirical resolution of the famous clock "paradox" with macroscopic clocks.
