"In the case of a Boeing 757 or 767, the pilot would be faced with an
EFIS (Electronic Flight Instrumentation System) panel comprised of six
large multi-mode LCDs interspersed with clusters of assorted “hard”
instruments. These displays process the raw aircraft system and flight
data into an integrated picture of the aircraft situation, position and
progress, not only in horizontal and vertical dimensions, but also with
regard to time and speed as well. When flying “blind”, I.e., with no
ground reference cues, it takes a highly skilled pilot to interpret, and
then apply, this data intelligently. If one cannot translate this
information quickly, precisely and accurately (and it takes an
instrument-rated pilot to do so), one would have ZERO SITUATIONAL
AWARENESS. I.e., the pilot wouldn’t have a clue where s/he was in
relation to the earth. Flight under such conditions is referred to as
“IFR”, or Instrument Flight Rules."

It was a clear sunny day so everything you said above is irrelavant.
Also it does not take an instrument rated pilot to do lok at the EFIS
and determine where you are. It is much easier to tell where you are
BECAUSE of the EFIS.




"According to FAA radar controllers, “Flight 77” then suddenly pops up
over Washington DC

The radar controller never said he popped up without warning.


and executes an incredibly precise diving turn at a
rate of 360 degrees/minute

There was nothing incredibly precise about it, or did there need to be.


while descending at 3,500 ft/min,

A descent of that rate is in the middle of the normal range for an airliner.


at the end
of which “Hanjour” allegedly levels out at ground level.

He didn't level out, he crashed into the building.


Oh, I almost
forgot: He also had the presence of mind to turn off the transponder in
the middle of this incredibly difficult maneuver

If you know where it is it's like turning off a light.

(one of his instructors
later commented the hapless fellow couldn’t have spelt the word if his
life depended on it)."

He was a foreigner, spelling was not second nature.



"The maneuver was in fact so precisely executed that the air traffic
controllers at Dulles refused to believe the blip on their screen was a
commercial airliner. Danielle O’Brian, one of the air traffic controllers
at Dulles who reported seeing the aircraft at 9:25 said, “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.”"

Because it was unexpecte, not because it was difficult.



"And then, all of a sudden we have magic. Voila! Hanjour finds the
Pentagon sitting squarely in his sights right before him."

Have you seen a picture of the area from the air? Antbody could pick
out the Pentagon.



"But even that wasn’t good enough for this fanatic Muslim kamikaze pilot.
You see, he found that his “missile” was heading towards one of the most
densely populated wings of the Pentagon—and one occupied by top military
brass, including the Secretary of Defense, Rumsfeld.

He wouldn't have any idea who occupied that part of the Pentagon.


Presumably in order
to save these men’s lives, he then executes a sweeping 270-degree turn
and approaches the building from the opposite direction and aligns
himself with the only wing of the Pentagon that was virtually uninhabited
due to extensive renovations that were underway (there were some 120
civilians construction workers in that wing who were killed; their work
included blast-proofing the outside wall of that wing)."

He did that because he was going to miss the building on his first attempt.



"I shan’t get into the aerodynamic impossibility of flying a large
commercial jetliner 20 feet above the ground at over 400 MPH.

Nothing impossible about it.

A
discussion on ground effect energy,

No such thing.


tip vortex compression,

You're making **** up.


downwash
sheet reaction,

Now that's just funny.



wake turbulence, and jetblast effects are beyond the
scope of this article

Wake turbulence and jet blast affect aircraft behind the one making it.


(the 100,000-lb jetblast alone would have blown
whole semi-trucks off the roads.)

Sure, if the trucks were within a couple hundred feet and the aircraft
was sitting on the ground. But a flying aircraft cannot blow any
vehicle over.



"Let it suffice to say that it is physically impossible to fly a 200,000-
lb airliner 20 feet above the ground at 400 MPH."

It's well within the capabilities of every airliner.







According to the article, the alledged hijackers would have had to be

No.
