Skyshield

September 9, 2010 - 12:12pm

Tomorrow marks the 50th anniversary of Operation Skyshield, one of the largest air drills in U.S. history. Operation Skyshield, which took place on Sept. 10, 1960, tested the ability of the U.S. to detect and defend against an assault by air. During the joint U.S.-Canadian military exercise, all civilian aircraft in North America were grounded. The exercise was repeated twice more–on Oct. 14 and 15, 1961, and a third time on Sept. 2, 1962.
