TWA Flight 514, registration N54328, was a Boeing 727-231 en route from Indianapolis, Indiana, and Columbus, Ohio, to Washington Dulles International that crashed into Mount Weather, Virginia, on December 1, 1974. All 85 passengers and 7 crew members were killed. During the NTSB investigation, it was discovered that a United Airlines flight had very narrowly escaped the same fate during the same approach and at the same location only six weeks prior. This was one of two Boeing 727s to crash in the United States that day; the other was Northwest Airlines Flight 6231.
