Notable aviation disasters in the 1990s included TWA Flight 800 crashing off the coast of Long Island, en route to Paris, France, on July 17, 1996 due to an explosion of the fuel tank, killing 230 and EgyptAir Flight 990 crashing south of Nantucket, Massachusetts, en route to Cairo, Egypt, on October 31, 1999 due to deliberate crashing by the first officer, killing 217. Shortly after the 9/11 terrorist attacks, the second-deadliest U.S. aviation incident occurred when American Airlines Flight 587 crashed in Queens, New York, en route to the Dominican Republic, on November 12, 2001 due to overuse of rudder controls by the pilot to counteract turbulence, killing 265 (including 5 on the ground).
