Charles F. Burlingame III, 51, of Herndon, Virginia, was the Captain of Flight 77, an aeronautical engineer, and a former Navy fighter pilot.
A graduate of the Naval Academy and the Navy's Top Gun fighter pilot school in Miramar, Calif. ...
... had been a Navy F-4 pilot and once worked on anti-terrorism strategies in the Pentagon ...
Like many military pilots, Burlingame considered the most difficult job to be landing an F-4 fighter jet on the deck of an aircraft carrier as it pitched at sea in the dark of night. After he left the Navy, Burlingame was hired by American Airlines in 1989.
Navy Vice Adm. Timothy Keating said Burlingame, who trained many pilots, "could make the jets talk. He could fly."
Microwave landing systems (MLS) were developed in the 1980s. These systems allow pilots to pick a path best suited to their type of aircraft and to descend and land from more directions than the ILS.
Helicopters have used visual landing procedures for most of their history, and on June 12, 1987, the FAA opened its national concepts development and demonstration heliport. This research heliport was fully equipped with items such as a microwave landing system as well as precision approach path indication lights like those used by fixed-wing aircraft.
Friends and family remembered him as a man who was unabashedly patriotic, who embraced military life even after he retired from active and reserve duty. He remained active in the reserve, working until 1996 as a liaison in the Pentagon (where he had worked for most of his 17 years as a Naval Reserve officer). When his plane went down Tuesday, it ripped through a section of the building that includes the Navy Reserve offices.
Mark Burlingame said his brother was in the Navy Reserve and had worked in the same area of the Pentagon where the airliner crashed.

What about taking into account distance from the camera F-4 is WAY smaller than a 757

beat me to maths
Okay, it's late in the evening so I didn't do it much exactly, rather some guesstimates with touch of maths here-there Maybe I'd make something more exact in the future.
Length of 757-200 is 47,32 meters
F-4 Phantom: 19,2 meters
Distance of impact point from camera: via the Google Map image measured it to be roughly 180 meters, ie 600 feet
Angle of attack - seen estimates 55-75 degrees, so settled up on average 65 degrees.
this of course means the object was a bit more far away on the camera, but let's not take it into account.
"Effective length" of 757 and F-4 Phantom (due to the angle) is smaller: l(ef) = l*sin65
angle dimensions of 757 and F4 from camera locations are:
angle = 2*arctan ((l(ef))/(2*180))
so it gives me for 757 roughly 13 degrees and for F-4 6 degrees.
Now the fuzzy part - using distance between the two "columns" (cannot find the correct word, sorry, those rectagonal coumns belonging to the gate right in front of the camera) determined the field of vision to be roughly 130 degrees.
Now the object's length fits almost entirely behind the right column, this gives me result of some 12 degrees.
This fits rather the 757-sized object.
I'd be glad if someone calcullates the field of vision more exactly, as I've said, it's late evening here and I really don't know why do I bother here instead of going to bed ... goodnight!
“60” of course is the critical angle in both equilateral triangles and the tetrahedra of which they are comprised -- the latter incorporating those same critical circumscribed 19.5-degree angles …
