Yeah, there is no evidence of a 757 crashing into the Pentagon. A good documentary is "In Plane Site" by David von Kleist. Here is a really good website:

Here are some excerpts from another site:
The Allure of the Unsolved Mystery
The question of what hit the Pentagon has remained a source of intense interest and debate for years now, overshadowing many other issues of the 9/11/01 attack. The controversy has thrived in the evidence vacuum created by official actions in the wake of the attack, which included the following:
· Minutes after the attack, the FBI seized from businesses adjacent to the Pentagon videos that likely recorded the event.
· On the day of the attack, Pentagon personnel participated in a rapid mop-up of the crime scene, moving and removing evidence before it could be documented.
· In the weeks following the attack, authorities controlled the crime scene, destroying or suppressing nearly all the physical evidence inside the building.
This left primarily two kinds of evidence: eyewitness reports consistent with the crash of a 757, and post-crash photographs taken by passers-by showing neither large aircraft debris nor an impact damage pattern expected from such a crash. The ambiguous and seemingly contradictory evidence made the event a kind of Rorschach, spawning many competing theories but offering no basis for definitive conclusions.
The mystery of the attack has lured researchers into endless debates, much to the detriment of public outreach around easily proved issues. Such issues include aspects of the Pentagon attack other than the question of what hit it. For example:
· The portion of the Pentagon targeted was mostly unoccupied due to a renovation program.
· The attack plane executed an extreme spiral dive maneuver to hit that portion of the building rather than the part housing high-level officials.
· The alleged pilot of Flight 77 was not competent to pilot a Cessna, let alone pilot a 757 through a maneuver that may have exceeded the skills of even the best test pilot.
Ignoring the Eyewitness Evidence
Proponents of the no-757-crash theory have tended to minimize the many eyewitness accounts that a 757-like aircraft flew into the Pentagon and exploded. Many simply cherry-pick one or two accounts that seem to indicate a much smaller plane, and ignore the larger body of eyewitness evidence.
This selective presentation of witness accounts is exemplified by a tendency to quote only a single phrase from a single witness: Mike Walter's use of "a cruise missile with wings." In context, it's clear that Walter was only using the cruise missile description metaphorically:
I looked out my window and I saw this plane, this jet, an American Airlines jet, coming. And I thought, 'This doesn't add up, it's really low'. I mean it was like a cruise missile with wings.
Another eyewitness account frequently cited as evidence that the attack plane was not an airliner is that of air traffic controller Danielle O'Brien:
The speed, the maneuverability, the way that he turned, we all thought in the radar room, all of us experienced air-traffic controllers, that that was a military plane.
That the controllers observed a plane being flown in a manner not normal for jetliner does not mean the plane was not a jetliner. Simple calculations show that the spiral dive attack maneuver was well within the capabilities of a Boeing 757. In fact, the body of eyewitness evidence provides almost no support for the no-757 theories, but does indicate that the event involved more than a simple plane crash, such as a sharp detonation wave not explainable by the crash of a jetliner. Once again, such substantial evidence that contradicts the official story has been eclipsed by the no-757-crash theory.
The "Physical Evidence" Case
Many apparent features of the crash that are documented by the photographs of the crash site -- and especially by photos taken before the overhanging section collapsed -- seem to support an overwhelming case against the crash of a 757. These features include the following.
1. The lawn shows no signs of gouging from a 757's low-hanging engines, despite eyewitness claims that the plane hit the ground before the facade.
2. The impact hole dimensions are not large enough to accommodate the entire profile of a 757.
3. The lawn shows almost no signs of crash debris immediately following the crash.
4. Photos from inside and outside the building during the recovery operation show very little aircraft debris.
5. Damaged columns remain standing where dense parts of the plane, such as the starboard engine, would have hit.
6. Unscored limestone and unbroken windows are visible in areas of the facade where the outer wings and vertical tail section of a 757 would have hit.
7. There is almost no debris such as suitcases or human bodies
8. There are obstacles in the plane's alleged flight path, such as cable spools.
This list is far from exhaustive. Many other features are often cited as evidence against a 757 crash, such as the positions of downed lamp-posts, the orientation of the damaged generator, and the position and shape of the C-ring punch-out hole. The number of no-757-crash arguments based on these features, and the logical independence of many of them, seem to many to constitute an overwhelming cumulative case against the crash of a 757. Whereas a deductive case is only as strong as its weakest argument, a cumulative case is as strong as the sum of its arguments. However, a cumulative case may appear strong without actually being so if it is composed entirely of arguments that evaporate under scrutiny. Let's examine four of the more persuasive arguments, which I've given the following labels:
· The missing wings and tail
· The vanishing jetliner
· The incorrect impact imprint
· The obstacle dodge
The Missing Wings and Tail
This argument, based on features 1, 2, and 3, holds that since the outer expanses of the wings and most of the vertical tail section of a 757 could not have fit through the facade's impact punctures, they should have been visible in the post-crash photographs of the building's exterior.
The argument makes the error of assuming that large pieces of the wings and tail should have remained intact. A crash study suggests that the over-300-mph impact of a jetliner with the Pentagon's heavy masonry facade would have reduced the entire aircraft -- and certainly its relatively light wings and tail -- to confetti.
Another error in this argument is its implicit assumption that the photographs of the Pentagon's lawn show it to be debris-free. In fact, the photographs have pronounced foreshortening of regions near the building, which, together with variations in the terrain, may hide significant debris fields.
The Vanishing Jetliner
This argument, based on features 3 and 4, holds that since there are no photographs showing large aircraft debris at the Pentagon, no jetliner could have crashed there. Recognizable pieces that were photographed, such as landing gear and engine parts, are few enough that they could have been planted.
This argument makes the error of the negative proof: the lack of evidence showing something's existence is taken as proof of its non-existence. The seeming disappearance of the 80-ton plane becomes much less mysterious when one considers two facts.
· As noted above, in similar crashes, the entire aircraft is converted to small confetti, most of which would be unrecognizable.
· There are few publicly available photographs of the interior of the building shortly after the crash. FEMA's investigative team was not allowed on the site until after all the debris had been removed.
The Incorrect Impact Imprint
This argument, based on features 5 and 6, holds that, since there is no impact imprint of a 757 on the Pentagon's facade, no such plane could have crashed there. In a crash at such a speed (over 300 mph) the wings and tail had too much momentum to deviate much from their trajectory even as the plane crashed into the facade. Therefore, even these relatively light parts should have at least scored the facade's rather soft limestone facing, and perhaps broken windows.
Even admitting that there are uncertainties about just how much damage the wing ends and tail of a 757 should have done to the Pentagon's facade, this argument is difficult to reconcile with the simple crash of a 757 -- at least of an intact 757. However, if the wing ends and tail were destroyed before impact, they might not have left impact impressions. That possibility is explored in the Unexamined Explanations section.
The Obstacle Dodge
This argument, based on feature 7, holds that the flightpath determined by downed light poles and eyewitness accounts takes the plane too low to have cleared obstacles near the building, such as several cable spools.
The spool that appears most problematic for the plane's supposed flightpath is the large upright one nearest the building. In most photographs it appears to be just a few feet from the building. However, appearances are deceiving given the foreshortening in the photographs. One article supporting the no-757-crash theory estimates that the large spool is about 28 feet from the facade. It also states that the diameter of the spool is 6 feet, 6 inches.
Given those coordinates and dimensions, and assuming the plane's trajectory was such that it was losing one foot of altitude for every ten feet of distance traveled, then the bottom of the plane's fuselage could have cleared the spool by a foot and crashed into the facade at an elevation of five feet, placing the bottoms of the engines at ground level. Contentions that turbulence from such a near miss would have toppled the spool are difficult to evaluate without knowing the weight of the spool, whether it was secured to the ground, and whether the spools rolled following the crash.
Unexamined Explanations
The last two arguments in the previous section illustrate just how easy it is to accept a pre-conceived conclusion from evidence while failing to consider other equally plausible explanations. I became convinced that the attack plane was not a 757 based primarily on those two arguments, and only later re-evaluated my conclusions in light of other possibilities.
An alternative explanation for the incorrect impact imprint consistent with the crash of a 757 was proposed by French researcher Eric Bart. He suggests that the jetliner was progressively shredded by explosives starting just as its nose was beginning to impact the wall. This theory explains the lack of impact impressions of the jetliner's extremities, since they would have been reduced to confetti before impact. It also accounts for the large punctures in the facade, since the remains of the plane's heaviest portions could have retained enough momentum to breach the walls and enter the building.
Bart's theory may sound far-fetched, and some detractors have compared it to the aggressively promoted idea that the South Tower was hit by a pod-equipped cargo jet that fired a missile just before impact. However, the comparison is not deserved. Whereas the pod-plane idea is based on imaginative interpretations of artifacts in blurry video images, Bart's theory reconciles the lack of imprint of the tail and wing ends with the overwhelming eyewitness evidence that a jetliner flew into the Pentagon and exploded. Several eyewitnesses even recalled details that seem to be explainable only by the plane being shredded before impact.
Bart's theory is consistent with the crash of Flight 77 at the Pentagon, but not with the official story that it was hijacked by Muslim terrorists, since it assumes the plane was prepared prior to the attack.
Other researchers, such as Stanley and Russell, have proposed that the Pentagon attack was engineered to make it appear that a 757 crashed when none had. Bart's theory reverses this, suggesting that the crash of a 757 was engineered to make it appear that no such plane had crashed.
The apparent motive for such a deception will likely escape 9/11 skeptics on both sides of the controversy about what hit the Pentagon. Most adherents to no-757-crash theories have ignored Bart's theory and the body of eyewitness evidence supporting it. Most opponents of no-757-crash theories have not looked closely enough at the impact damage pattern to see a problem reconciling it with the simple crash of a 757. This is exactly the conflict that the engineered crash may have been designed to create. Experts at psychological operations, the perpetrators could have anticipated that skeptics would divide into two groups: those persuaded by eyewitness evidence that a 757 had crashed, and those persuaded by physical evidence that one had not. The ongoing controversy could then be exploited by the perpetrators to several ends:
· to keep the skeptics divided
· to divert skeptics' resources from other more productive lines of inquiry
· to provide a bizarre-sounding theory with which to tar the entire 9/11 Truth Movement
If you accept the premise that the crash of a 757 was engineered to create seemingly contradictory bodies of evidence in order to seed truth-obfuscating conflicts, it is easy to explain crash-site anomalies beyond the facade impact imprint. For example, the spool that is arguably a problem for the plane's approach could have been stood up immediately after the crash to bolster the anticipated no-757-crash theory. While this may seem far-fetched, it is much less far-fetched than suppositions of no-757-crash theorists, such as that the downing of the highway lamp-posts was engineered independent of the attack plane.
