During the September 11 attacks , American Airlines Flight 11 flew near the Indian Point Energy Center en route to the World Trade Center . Mohamed Atta , one of the 9/11 hijackers/plotters , had considered nuclear facilities for targeting in a terrorist attack . Entergy says it is prepared for a terrorist attack , and asserts that a large airliner crash into the containment building would not cause reactor damage . Following 9/11 the NRC required operators of nuclear facilities in the U.S. to examine the effects of terrorist events and provide planned responses . In September 2006 , the Indian Point Security Department successfully completed mock assault exercises required by the Nuclear Regulatory Commission . However , according to environmental group Riverkeeper , these NRC exercises are inadequate because they do not envision a sufficiently large group of attackers
