On this day in history, December 7, 1941, started as a typical Sunday morning at Pearl Harbor, the U.S. Navy’s Pacific Fleet Headquarters on the Hawaiian island of Oahu.  That is, until shortly before 8 a.m., when Japan launched roughly 200 planes from six aircraft carriers in its first wave of Operation Hawaii—forever to be known by Americans as “the attack on Pearl Harbor” or just “Pearl Harbor.”
