I want to know the answer to the following question:
What aircraft was hijacked?
All the background I'm provided with is that "Lieutenant General Timothy Maude was the highest-ranking military official killed at the Pentagon, and the most senior U.S. Army officer killed by foreign action since the death of Lieutenant General Simon B. Buckner, Jr. on June 18, 1945, in the Battle of Okinawa during World War II.". Is that enough to answer the question?
