United Airlines Flight 93, a Boeing 757, departs Newark International Airport at 8:01 a.m. ET en route to San Fransisco with 44 people on board. The plane is hijacked and makes an immediate u-turn just south of Cleveland. As the plane heads toward an unknown target - possibly Camp David, Air Force One, the White House or another location in Washington, D.C. - it drops from the sky and crashes at 10:10 a.m. just north of the Somerset County airport, about 80 miles southeast of Pittsburgh.
