The two F-15 fighter jets that launched from Otis Air National Guard Base in Cape Cod, Massachusetts, in response to the hijacked Flight 11 (see 8:46 a.m. September 11, 2001) land back at their base after flying a combat air patrol (CAP) over New York City. [Aviation Week and Space Technology, 6/3/2002; Filson, 10/2/2002] The F-15s, which belong to the 102nd Fighter Wing of the Massachusetts Air National Guard, are piloted by Major Daniel Nash and Lieutenant Colonel Timothy Duffy. [Rosenfeld and Gross, 2007, pp. 35]
Fighters Intercepted about 100 Aircraft – Duffy and Nash’s job during the CAP was to identify and divert all aircraft from the Manhattan area. Duffy will later recall, “We would pull up next to them and tip our wings or fly across in front of them to get them to leave the area.” [102nd Fighter Wing, 2001; 9/11 Commission, 1/7/2004 ] He will say that during their time flying over Manhattan, “All of the sudden, you get contacts coming toward the city that are unidentified and aren’t talking to anybody, and we were getting real nervous.” [Filson, 10/22/2002] Duffy will estimate that the two fighters intercepted and escorted about 100 aircraft in total, including emergency, military, and news helicopters, plus dozens of small private planes whose pilots were unaware of the attacks on New York. Some of those pilots had seen the smoke over the city and decided to investigate. [Aviation Week and Space Technology, 6/3/2002; Cape Cod Times, 8/21/2002]
One Fighter over Manhattan at All Times – Duffy and Nash had alternated their responsibilities, so that one of them would remain over Manhattan at all times while the other would intercept aircraft or be refueled by a tanker plane over the ocean (see (Shortly After 9:35 a.m.) September 11, 2001). After flying the CAP for about two hours, they were joined by a couple more F-15s from Otis Air Base (see (11:00 a.m.-6:00 p.m.) September 11, 2001). While those jets flew at around 18,000 feet, Nash and Duffy remained at around 10,000 feet. [Cape Cod Times, 8/21/2002; Filson, 10/2/2002; Filson, 10/22/2002; 9/11 Commission, 1/7/2004 ] Eventually, after several hours flying over Manhattan, Nash and Duffy were ordered to return to their base.
Base Hectic with Activity – Upon landing, they find that Otis Air Base is very different to how it was when they took off. Rows and rows of their unit’s fighters are lined up near the runway, surrounded by about 100 maintenance personnel who are frantically working to prepare the aircraft for battle. [Spencer, 2008, pp. 273-274] Armed security officers in flak jackets are guarding every entrance to the base; personnel are swarming in the buildings; and officers are trying to locate all the reserve pilots.
Pilot Learns of Pentagon Attack – The two fighter pilots had been poorly informed about what was going on regarding the terrorist attacks, and were only told in passing by an air traffic controller that there had been an attack in Washington (see (8:53 a.m.-10:30 a.m.) September 11, 2001). After he gets out of his plane, Nash is informed by a crew member that an aircraft crashed into the Pentagon. [Cape Cod Times, 8/21/2002; Michael Bronner, 2006] Nash and Duffy subsequently go to their unit’s “intelligence shop” and describe what they have done since taking off from the base hours earlier.
