The four aircraft involved in the 9/11 attacks departed from which combination of airports?

• A. Two from Boston, Newark & Dulles
• B. All four from New York area airports
• C. Boston Logan, Newark, and Dulles only
• D. Two from Boston, one from Newark, one from Dulles

Answer: (A)

The planes departed from three airports in total: two from Boston Logan International Airport, one from Newark Liberty International Airport, and one from Dulles International Airport. This distribution matches the historical record: AA11 and UA175 originated at Boston Logan, UA93 from Newark, and AA77 from Dulles. The other options misstate either the number of airports involved or the distribution of departures, so they don’t reflect what actually happened.
