What were the departure points of the four aircraft on 9/11?

• A. All four flights departed from Boston Logan
• B. Two from Boston, Newark & Dulles
• C. One from each of the four major hubs
• D. Two from Boston, two from Newark and Dulles

Answer: (B)

The situation tests knowledge of where each of the four planes originated. In reality, the planes came from three airports: two from Boston Logan, one from Newark Liberty, and one from Washington Dulles. Specifically, two flights departed Boston Logan (American Airlines Flight 11 and United Airlines Flight 175), one departed Newark (United Airlines Flight 93), and one departed Dulles (American Airlines Flight 77). That distribution—two from Boston, one from Newark, one from Dulles—matches the stated answer exactly. The other options would misstate the real departure pattern, such as claiming all four left Boston, or suggesting a different spread among the airports.
