A day of remembrance in honor of the 2,400 Americans who died at Pearl Harbor.

At 7:48 a.m. on December 7, 1941, 353 Japanese fighter planes bombed U.S. air bases across the Hawaiian island of Oahu. At that moment, what in some alternate universe might have been a peaceful Sunday morning, turned into what Franklin Delano Roosevelt called “a day that will live in infamy.”
