    Somerset 366k
    United Airlines Flight 93 was a domestic scheduled passenger flight that was hijacked by four Al-Qaeda terrorists on board, as part of the September 11 attacks. It crashed into a field near the Diamond T. Mine in Stonycreek Township, Somerset County, Pennsylvania, near Indian Lake and Shanksville, during an attempt by some of the passengers to regain control, killing all 44 people aboard including the four hijackers. No one on the ground was injured. The aircraft involved, a Boeing 757222, was flying United Airlines' daily scheduled morning domestic flight from Newark International Airport in New Jersey to San Francisco International Airport in California.
