this airliner?
and in this picture you can clearly see the plane ploughing into the pentagon apparently
I'm not even going to bother typing my own reply to this one, let me quote directly from Urban Legend .....
The argument is weak. For starters, it conveniently ignores some of the most obvious, compelling evidence. For example:
Eyewitness testimony of bystanders who saw and/or heard American Airlines Flight 77 approach and collide with the Pentagon
The recovery of both black boxes belonging to the Boeing 757 from the Pentagon wreckage
The recovery and identification of the remains of all but one of the people known to be aboard Flight 77.
Of course, evading bedrock evidence is standard procedure for conspiracy theorists. If pressed, they would doubtless claim that all of the above must have been planted or manufactured, but they can't even prove such a claim plausible, let alone true beyond a reasonable doubt.
An improbably successful cover-up
Make no mistake, the burden of proof is on the conspiracy theorists, whose case presupposes that all of the hundreds of people who participated in the clean-up, recovery and investigation following the 9/11 Pentagon attack including scientists, engineers, coroners and professional air disaster investigators are either dead wrong or participating in a massive, improbably successful government cover-up.
Eschewing plain facts and common sense, the conspiracy theorists ask us to focus instead on misleadingly posed condundrums such as the following:
Question: "Can you explain how a Boeing 757-200, weighing nearly 100 tons and travelling at a minimum speed of 250 miles an hour only damaged the outside of the Pentagon?"
Answer: It didn't only damage the outside. According to the Washington Post, structural damage extended at least 150 feet inside, well into the third ("C") ring of the building.
Question: "Can you explain how a Boeing 14.9 yards high, 51.7 yards long, with a wingspan of 41.6 yards and a cockpit 3.8 yards high, could crash into just the ground floor of this building?"
Answer: It didn't just crash into the ground floor. According to official statements and news reports, it took out both the first and second floors on impact.
Question: "Can you find debris of a Boeing 757-200 in this photograph?"
Answer: No, but we can in this one credited to a U.S. Navy photographer [enlarged version]. Bear in mind, eyewitnesses say the Boeing 757 virtually disintegrated when it struck the reinforced wall of the building. Given that, and the tremendous forward momentum of the aircraft on impact, the assumption that a significant amount of debris ought to be visible in front of the Pentagon wouldn't seem justified.
According to a CNN article published the day after the attack, Michael Tamillow, a battalion chief of the Fairfax County, Virginia Fire Department, reported that parts of the Boeing 757 fuselage had indeed been recovered from the wreckage by FBI investigators (the same team that later found the black boxes). "No large pieces apparently survived," the article said.
One visitor who surveyed the crash site a few days later, Representative Judy Biggert of Illinois, told reporters she saw remnants of the jetliner: "There was a seat from a plane," she said, "there was part of the tail and then there was a part of green metal, I could not tell what it was, a part of the outside of the plane."
