Early on the morning of Tuesday, September 11, 2001, nineteen hijackers took control of four commercial airliners (two Boeing 757s and two Boeing 767s) en route to California after takeoffs from Logan International Airport in Boston, Massachusetts; Newark Liberty International Airport in Newark, New Jersey; and Washington Dulles International Airport in Loudoun and Fairfax counties in Virginia.[118] Large planes with long flights were selected for hijacking because they would have more fuel. Atta said to hijack Boeing aircraft based on his understanding of the autopilot feature.
