Aus 9/11 Wiki
Ronald Galey has claimed he was still on the ground at the aviation unit at Reagon National Airport at the time the Pentagon was hit, and he was therefore able to answer the call on the aircraft crash phone in which the crash was reported.  However, Galey has given conflicting accounts about what the air traffic controller at Reagan Airport, David Walsh, supposedly told him in the call. 
In November 2001, Galey recalled Walsh saying, "We have a 757 down somewhere in the vicinity of the 14th Street Bridge," which goes over the Potomac River, near the Pentagon.  Later that month, Galey gave a slightly different account, recalling that Walsh said the control tower had "lost a 757 somewhere in the vicinity of the Pentagon."  But in January 2002, Galey said that Walsh specifically mentioned a plane hitting the Pentagon. Walsh supposedly said that "they had a 757 go into the Pentagon and they needed us to respond to the incident." 
And then, later that year, Galey gave a very different account. He recalled Walsh saying, "We have a 757 down on the north end of the airport," referring to Reagan Airport, which is about a mile away from the Pentagon.  Galey's fellow pilot, Keith Bohn, had earlier given a similar account. In November 2001, he said that in the initial phone call the aviation unit received about the attack, it was told there was "an aircraft down at the end of the runway at National Airport."
