I myself am a licensed pilot and find his explanations quite plausible. A novice pilot puts the plane into a dive, but doesn't remember to compensate for the increased lift which is caused by the increased speed. So he overshoots the target, and then has to go into a tight 270 degree turn to avoid losing the target completely.

Point taken, and of course, you're right. However, TheStateInc claims these guys were not really novices, and if they were [and did what this pilot suggested any novice would do], this pilot forgets they were in a large turbine aircraft and being such novices, would have lost the aircraft. Not to mention no ATP is going to give up his airplane to a few CLOWNS with boxcutters and half-inch blades, regardless of their verbal threats.

So it can't be both ways. They either had to be PROS, or, if they were so inexperienced to be surprised by the increased lift and speed produced by a descent, they would have never have made it. TheState and their propaganda mouthpieces keep wanting to have it both ways, depending on what point they're trying to discredit.

From what I can recall about the path of desent, there wasn't a "dive" into or toward the Pentagon. The controllers reported a smooth 270-330 degree circle desent that took the aircraft right above the ground and smack into the empty side of the Pentagon.

No DNA has ever been matched or linked to said hijackers.

One more question.

The airliner didn't strike short, and there are no accounts of a high speed "dive" that then resulted in a "overshooting" and then a sweeping 270 degree loop.

The aircraft hit exactly where it was planned to hit, where it would cause minimum damage and loss of life.

From what I can recall about the path of desent, there wasn't a "dive" into or toward the Pentagon.

The Pentagon is almost at sea level, and the aircraft was over 5,000 feet when it started its descent. That is a dive for an aircraft that large and generating that much lift.

The controllers reported a smooth 270-330 degree circle desent that took the aircraft right above the ground and smack into the empty side of the Pentagon.

From the link:

"I based the turn radius on a 275 knot airspeed, since I doubt the airplane would have sufficient power and structural integrity to fly at 500 knots at low altitude. And unless the pilot had a lot of experience flying large airplanes at high speeds low to the ground, he would have avoided making a steep bank, so I based my turn radius on a 30 degree bank angle."

That isn't what was reported by the actual FAA controllers, and according to your link, the flight path isn't even lined up with the Pentagon.

The path of the airliner is exactly what was intended.

So then an inexperienced pilot "overshot" the Pentagon, then took the aircraft, made a 270 degree circle, and flew it 40-60ft above the ground, and smack the empty side of the Pentagon?

Like you said, its pure speculation.

Again, your stand on 911 is what?

And alleging "The path of the airliner is exactly what was intended" isn't?

Again, your stand on 911 is what?

(1) There are many people who believe their passsionate and opinionated views on 911 can compensate for their lack of knowledge about technical details of various subjects pertaining to the details of 911,

(2) There are 2 sides that want war in the Middle East, not 1, and

(3) Certain small elements of individuals on the side associated with the US and Israeli governments had a pretty good idea of what was going to happen, wanted it to happen, and did nothing to prevent it from happening.

Your depiction of the flight path is not even close to the flight path reported by the NTSB Flight 77 Flight Path Study. You can find it at the link above on page 5.

Consider the NTSB report. Hanjour rolls out on the final attack approach flying less than 50 feet above irregular terrain knocking down 5 light poles flying at over 450 knots.

The aircraft was headed in the general direction of Reagan International Airport and the Pentagon, which are only a few miles apart.

Plus, they had their transponders off, which begs the question of how exactly the NTSB could come up with a precise flight path of any sort.

Also, it's not me who's been making such a big deal of an alleged "270 degree turn."

That would support a contention of a somewhat erratic flight path as he meanders around looking for his target - which was a building complex low to the ground and away from major landmarks.

POSSIBLY, the FAA radar could have picked up an aircraft as a "primary return" - no transponder. Since the FAA insists that it saw the altitude, the transponder would need to be on. Lacking any TCAS warnings, there could have been no transponder - Flight 77 is a total fake, as to the crash.

BUT - where did it end up?

There's the 64,000 dollar question.

I did find it interesting that the NTSB claimed they were releasing the recovered data from the FDR, but neglected to release the radio altimeter data which is a parameter that the FAR's require the equipment to record.

The radio altimeter gives the height of the bottom of the aircraft to the ground in feet.

Funny you should mention that. I was just going to ask you a question about that since you seem to know your chit.

OK, they adjusted the altimeter on the way up through 18,000, by they I mean the flight crew, yes?

So now some dimbulb hijacker is supposed to have taken over and flown the plane to DC and he is going to vaporize himself by flying into the pentagon...

Is he going to remember to reset the altimeter on the way back down past 18,000ft? Is he going to remember to do that under the stress involved in knowing he's going to be vaporizing himself.

And how would he know the correct barometric pressure to adjust the altimeter? Would he call Dulles on the radio? Or is that something that is just broadcast from an airport continuously?

If one wants to take the data seriously, it must be assumed that the altimiter setting would be immaterial to the events ahead, during the descent. Normally, the crew would tune into an automated broadcast (ATIS), to get the local altimeter setting.

The flight data should indicate the GPWS (Ground Proximity Warning System) warnings, based on the radar altimeter.

Funny, there is no mention of that!

Sky, I know you are familiar with the information in my comments below,I am adding them to expand on your point that the setting is immaterial.

The FDR records pressure altitude,Parameter 2.The altimeter setting is unrelated to the measurement of pressure altitude.

To use the recorded pressure altitude to determine height above mean sea level (MSL), a correction is applied based on the local altimeter setting.

As far as the pressure altitude parameter recorded by the FDR,it simply does not matter what altimeter setting is set on the altimeter.

Correct; I was addressing the pilots procedures. The FDR is a very sophisticated recording device.

It should be added that the navigation units have an emergency cache of position data, also. That can be accessed independently - if it survives.

Dumb dumb hijacker about to vaporize himself and not used to flying above FL180, would probably not KNOW to reset altimeter from 29.92 back to current barometric pressure when crossing 18,000 feet, if he did he would have had to listen to an automated ATIS broadcast to get the reading [or just monitor ATC]...and furthermore he would NOT be the least bit concerned with doing so. Obeying regulations when your about to die??? In the vid, the missile...ahh I mean the hijacker did NOT bother resetting the altimeter which means the alledged NTSB info about altitude is a lie and the aircraft was really a few hundred feet higher AGL [above the ground], which is what I believe the video exposes. [Crossing from higher pressure to lower pressure without resetting your altimeter will cause the altimeter to read higher than you really are above the ground [AGL] and vice versa.

So if one descends from 29.92 to an area of higher pressure without resetting, the altimeter will read lower than you really are which means you will really be higher AGL. In others words as the pressure increases, if you do not reset the altimeter, you will have been steadily getting higher above the ground.]

For example, if one were making an non-precision instrument approach in poor conditions, and the decision height is posted as 5000 MSL [200 AGL..so the airport runway is at 4800 ft] from 29.92 to the correct LOWER actual pressure of say 28.99, the aircaraft altimeter reading will be higher than you really are..decision height will NOT really be at 200ft above the ground but your airplane will be much LOWER...and then much likely resulting in obstacle or ground contact short of the runway.

You just got your first free ground school lesson :)

As per pilots for 911 truth, and testimony from instructors, these dummies would have been able to look at an altimter and know to set it to whatever ATC tells them to, but they didn't have any earthly idea as to WHY. The above info must be explained, depending on which question the examiner decides to ask, on the verbal exam before the Instrument Rating checkride, and also on the Commercial. It depends on the examiner. It's also on the written exam for BOTH.

Parameter 39- Lattitude and Longitude

OK, then if you want to accept the NTSB report there is really nothing that would require any high-level flying skills.

Some of the stories out there allege the aircraft made a "270 degree precision turn" requiring the skills of a "crack fighter pilot."

However, according to the NTSB, the maneuver was a 330 degree descending turn that started at 7,000 feet @ 9:34 and ended at 2,000 feet @ 9:37. So the pilot had 3 minutes to lose 5,000 feet and line up for the Pentagon, which was only 3.5 miles from the beginning, and 4 miles from the end, of the turn.

The flight path shows that Reagan Airport was always straight ahead of the plane before the final maneuvers started. So the NTSB report makes it appear the pilot used the autopilot to navigate straight towards Reagan Airport, disconnected the autopilot when he acquired his target visually, went down to 7,000 feet until he was within 5 miles, then took 3 minutes to lose 5,000 feet and line up for the final impact. I don't see anything terribly complicated in any of that. Safe landings are the most complicated part of flying any aircraft.

BTW, I used to subscribe to a number of aviation safety publications including Aviation Safety and the NTSB Reporter. There were several articles about how sometimes experienced airline pilots do poorly on flight tests with smaller aircraft, because the smaller planes are not as automated and more susceptible to various environmental factors such as wind and turbulence.

So the stories about Hanjour not being able to pilot a Cessna 172 too well, may not be any indication of how well he could have done taking over a larger passenger aircraft through the air without attempting any landing.

I regularly fly Boeing jets into some of the most challenging airports in the world.I've been flying for over 20 years.

Flying consistently at less than 50 feet AGL over irregular terrain avoiding numerous obstacles at over 400 knots for over a half of a mile is beyond my skill level.

And at 460 knots, you'd cover that half mile in under 4 seconds.

Loading the FDR data from Flight 77 into a 757 simulator and replaying the profile would be a worthwhile endeavor. Hopefully it will be done one day.

And at 460 knots, you'd cover that half mile in under 4 seconds.

On a Category III approach flown to minimums, the time from the point you can see the runway until touchdown is about four seconds.It seems like a very short time period but precise control inputs are required to accomplish a safe landing at about 150 knots.In my view, very precise control inputs would have been required to compensate for the effects of striking five light poles and not hitting the ground or climbing above the height of the 50 ft light poles.

That's where, in my opinion, ground effect comes in.

When you're landing, you have your gear and flaps down and lots of drag from them. The Flight 77 aircraft was coming in clean there wasn't much drag to interfere with ground effect. I'd think you'd have to really push hard on the controls to make it go down any further.

Radar data shows Flight 77 crossing the Capitol Beltway and headed toward the Pentagon. However, the plane, flying more than 400 mph, is too high when it nears the Pentagon at 9:35 a.m., crossing the Pentagon at about 7,000 feet up. [CBS News, 9/21/2001; Boston Globe, 11/23/2001] The plane then makes a difficult high-speed descending turn. It makes a “downward spiral, turning almost a complete circle and dropping the last 7,000 feet in two-and-a-half minutes. The steep turn is so smooth, the sources say, it’s clear there [is] no fight for control going on.” [CBS News, 9/21/2001] It gets very near the White House during this turn. “Sources say the hijacked jet ... [flies] several miles south of the restricted airspace around the White House.” [CBS News, 9/21/2001]

Then I noticed the aircraft. It was an unidentified plane to the southwest of Dulles, moving at a very high rate of speed … I had literally a blip and nothing more."

O'Brien asked the controller sitting next to her, Tom Howell, if he saw it too.

"I said, 'Oh my God, it looks like he's headed to the White House,'" recalls Howell. "I was yelling … 'We've got a target headed right for the White House!'"

At a speed of about 500 miles an hour, the plane was headed straight for what is known as P-56, protected air space 56, which covers the White House and the Capitol.

"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," says O'Brien. "You don't fly a 757 in that manner. It's unsafe."

The plane was between 12 and 14 miles away, says O'Brien, "and it was just a countdown. Ten miles west. Nine miles west … Our supervisor picked up our line to the White House and started relaying to them the information, [that] we have an unidentified very fast-moving aircraft inbound toward your vicinity, 8 miles west."

Vice President Cheney was rushed to a special basement bunker. White House staff members were told to run away from the building.

"And it went six, five, four. And I had it in my mouth to say, three, and all of a sudden the plane turned away. In the room, it was almost a sense of relief. This must be a fighter. This must be one of our guys sent in, scrambled to patrol our capital, and to protect our president, and we sat back in our chairs and breathed for just a second," says O'Brien.

But the plane continued to turn right until it had made a 360-degree maneuver.

At the Dulles tower, Danielle O'Brien also saw the TV pictures from New York and headed back to her post, now to help other planes quickly land.

Ms. O'BRIEN: We started moving the planes in as quickly as we could. Then I noticed the aircraft. It was an unidentified plane to the southwest of Dulles moving at a very high rate of speed. I had literally a blip and nothing more. I slid over to the controller on my left, Tom Howell, and I asked him, 'Do you see an unidentified plane there southwest of Dulles?' And his response was, 'Yes. Oh, my gosh, yes! Look how fast he is.'

Mr. TOM HOWELL: And then I said, 'Oh, my, god. It looks like he's headed to the White House.' I started yelling, 'John! John! We've got a target headed right for the White House.'

ROSS: (VO) A representation of the FAA radar scope, based on information obtained by 20/20, shows the plane headed straight for what is known as P-56, Prohibited Air Space 56, which covers the White House and the Capitol, at a speed of about 500 miles an hour with no radio contact whatsoever.

(OC) Was he on a normal flight approach of any kind?

Ms. O'BRIEN: Not at all.

ROSS: Full throttle.

Ms. O'BRIEN: Full out.

ROSS: How far out was that plane?

Ms. O'BRIEN: Between 12 and 14 miles. John, our supervisor, relayed verbatim. 'OK, he's 12 miles west, he's moving very fast eastbound

The NTSB report on Flight 77 describes the plane's maneuvers in detail. It began to turn to the south at 8:55, and by 9:00 it was headed east. Shortly thereafter it began to descend from its altitude of 35,000 feet. The autopilot was engaged and disengaged multiple times. At 9:29 the plane was 35 miles west of the Pentagon flying at 7,000 feet. At 9:34 it was about 3.5 miles west-southwest of the Pentagon and started a 330-degree descending right turn, bringing it to an altitude of about 2000 feet four miles southwest of the Pentagon. 3

'Pentagon Attack Maneuvers Preclude a 757' A fact frequently cited as evidence that the aircraft that attacked the Pentagon on 9/11/01 was not Flight 77, a Boeing 757, is that the aircraft tracked by air traffic controllers made a spectacular spiral dive, loosing 7000 feet and turning 270 degrees in about 2.5 minutes -- a maneuver alleged to be impossible for a 757. A September 12, 2001 CBS News report described the maneuver:

Radar shows that Flight 77 did a downward spiral, turning almost a complete circle and dropping the last 7000 feet in two-and-a-half minutes.

Air traffic controller Danielle O'Brien told ABC News that the maneuver was not one expected of a jetliner:

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. 1

However, the fact that the plane was being flown in a manner not typical for a jetliner does not mean it was not a jetliner. A 757 is capable of rather extreme maneuvers: It is capable of taking off on one engine, and can execute pitch accelerations of over 3.5 Gs (gravities) as demonstrated by the following incident report of an IcelandAir 757-200:

REPORT 7/2003 - Date: 22 January 2003 serious incident to icelandair BOEING 757-200 at oslo airport gardermoen norway 22 january 2002

... 1.1.14.5 At this time the First Officer called out PULL UP! - PULL UP!. The GPWS aural warnings of TERRAIN and then TOO LOW TERRAIN were activated. Both pilots were active at the control columns and a maximum up input was made. A split between left and right elevator was indicated at this time. It appears the split occurred due to both pilots being active at the controls. The pilots did not register the aural warnings. During the dive the airspeed increased to 251 kt and the lowest altitude in the recovery was 321 ft radio altitude with a peaked load factor of +3.59 gs. 2

How does this apply to the 2.5 minute 270- degree spiral turn? The G forces produced by such a turn can be calculated using the following formula.

RCF = 0.001118 * r * N^2 where RCF = Relative Centrifugal Force (gravities) r = rotation radius (meters) N = rotation speed (revolutions per minute)

If the plane were traveling at 400 miles per hour it would travel 16.666 miles, or 26,821 meters, in 2.5 minutes. Assuming it was traveling in a circular arc, it would trace out 3/4ths of a circle with a 35,761-meter circumference, giving a rotation radius of 5,691 meters and rotation speed of 0.3 rotations per minute. Plugging those values into the above equation, we obtain a centrifugal force of 0.5726 Gs -- hardly a problem for a 757 whose rated G limits are over two.

Final Approach Also cited as evidence against 757 involvement in the attack is the shallow descent angle of the aircraft as it made its final approach of the Pentagon. Photographs show no signs of gouging of the lawn by a 757's low-hanging engines, even though direct impact damage was limited to the first and second floors of the building. How could such a large aircraft be flown so close to the ground, and with such precision?

Two distinct questions are implicit in the previous one.

Were alleged hijackers capable of piloting the airliner through the maneuvers? Could a 757-200 perform the maneuvers? Hani Hanjour may not have been up to the task, but a 757's flight control computer seems sufficient. It's equipped with radar altimeters and accurate GPS monitors for precise altitude and position tracking. It can analyze and respond to conditions hundreds of times per second. Examples of the extreme capabilities of fly-by-wire systems are reverse swept-wing aircraft, which are inherently unstable and require rapid adjustment of the plane's control surfaces.
