Sept. 11 flight attendants provided vital clues

　　JULY 19 — Two flight attendants* on the American Airlines plane that crashed* into the World Trade Center gave important details that helped the FBI identify* the terrorists*.The crucial roles played by flight attendants Amy Sweeney and Betty Ong have emerged for the first time.The two on the Boston-Los Angeles flight fed a steady flow of information to the carrier’s ground staff* until seconds before it hit the north tower.“Listen and listen to me very carefully. I am on Flight 11. The airplane has been hijacked*,” Sweeney told ground manager Michael Woodward.Sweeney spoke “very, very calmly — in a way which was quick but calm,” Woodward told ABC News, adding that she gave him the seat numbers of four of the five hijackers.That allowed airline staff to find the terrorists’ names, phone numbers, addresses and credit-card numbers.One of the names was ringleader* Mohamed Atta. That was the key link that tied the attacks to Osama bin Laden and his al-Qaida* network.Sweeney told Woodward how the hijackers had stabbed* the two first-class attendants and slashed the throat of a business-class passenger.Woodward asked Sweeney to look out of the window and see if she could tell what was happening.“I see the water. I see the buildings. I see buildings,” she told him, adding that the plane was flying very low. “She took a very slow, deep breath and then just said, ‘Oh, my God!’ Very slowly, very calmly, very quietly. It was not in a panic*.” (Difficulty: junior)Questions:Write T for True and F for False according to the article.1.
