I know a lot of opinion of professional pilots about the attack on the Pentagon and therefore I can not believe what you say. Some examples:
Commander Ted Muga, BS CE, U.S. Navy (ret) – Retired Pan-Am commercial airline pilot. Commercial aircraft flown: Boeing 707 and 727...
« The maneuver at the Pentagon was just a tight spiral coming down out of 7,000 feet. And a commercial aircraft, while they can in fact structurally somewhat handle that maneuver, they are very, very, very difficult. And it would take considerable training. In other words, commercial aircraft are designed for a particular purpose and that is for comfort and for passengers and it's not for military maneuvers. And while they are structurally capable of doing them, it takes some very, very talented pilots to do that. ...
When a commercial airplane gets that high, it gets very, very close to getting into what you refer to as a speed high-speed stall. And a high-speed stall can be very, very violent on a commercial-type aircraft and you never want to get into that situation. I just can't imagine an amateur even being able to come close to performing a maneuver of that nature. »

Commander Ralph Kolstad, U.S. Navy (ret) – Retired commercial airline captain with 27 years experience. Aircraft flown: Boeing 727, 757 and 767...
« At the Pentagon, the pilot of the Boeing 757 did quite a feat of flying. I have 6,000 hours of flight time in Boeing 757’s and 767’s and could not have flown it the way the flight path was described. »
Capt. Russ Wittenberg, U.S. Air Force – Retired commercial pilot. Flew for Pan Am and United Airlines for 35 years. Aircraft flown: Boeing 707, 720, 727, 737, 747, 757, 767...
Article 7/17/05: "The government story they handed us about 9/11 is total B.S. plain and simple." … Wittenberg convincingly argued there was absolutely no possibility that Flight 77 could have "descended 7,000 feet in two minutes, all the while performing a steep 280 degree banked turn before crashing into the Pentagon's first floor wall without touching the lawn."…
"For a guy to just jump into the cockpit and fly like an ace is impossible - there is not one chance in a thousand," said Wittenberg, recalling that when he made the jump from Boeing 727's to the highly sophisticated computerized characteristics of the 737's through 767's it took him considerable time to feel comfortable flying."
« Audio Interview 9/16/04: Regarding Flight 77, which allegedly hit the Pentagon. "The airplane could not have flown at those speeds which they said it did without going into what they call a high speed stall. The airplane won’t go that fast if you start pulling those high G maneuvers at those bank angles. … To expect this alleged airplane to run these maneuvers with a total amateur at the controls is simply ludicrous.. »

Quote: « After the attacks, for example, aviation experts concluded that the final maneuvers of American Airlines Flight 77 -- a tight turn followed by a steep, accurate descent into the Pentagon -- was the work of "a great talent »
Markus Kirschneck, from the pilots-association "Cockpit" « "The Pentagon-Maneuver was one of the most difficult maneuvers you could do with a passengers-jet at all."
Ralph W. Omholt – Commercial airline pilot. Aircraft flown: Boeing 727, 737, 747, 757, 767...
Quote: « At the 9-11 Pentagon, we are supposed to believe that a 757, traveling at 300 Knots dove over a batch of construction equipment, immediately adjacent to the Pentagon wall, then leveled out; and did a totally perfect strike at the convenient “Least-Risk Point.” Thereafter, it morphed its way through three rings of the Pentagon, turning left and right through the linking hallways, leaving a handful of aircraft pieces which defy accountability. All that, without damaging or burning the Pentagon lawn! All that by a pilot known to be an idiot at the controls of a small plane. It's more than IMPOSSIBLE: it's absurd! »
« One pilot correctly claims that hitting the building, itself, would be easy.No doubt about it; it's a huge building. But no pilot with any degree of dignity will claim to be able to hit such a spot as the Pentagon base – under any conditions – in a 757 doing 300 Knots. As to the clearly alleged amateur pilots: IMPOSSIBLE! »
(Note: The speed of the final maneuver of flight 77 was supposedly 530 miles per hour, ie 460.55 Knots per hour)
« Add the aerodynamic issue of "Ground Effect." A high-speed wing would create a compression layer between the wing and the ground. The wing could NOT descend into that "Ground Effect" region, without the aircraft being in a pronounced dive - which is an impossibility - relative to the "official" story. Such a dive would have left a distinctive seismic impression (below); and a crater. »
