A great comment by AaronKM on my this article, to a person who was making ad hominem statements and then cowardly blocked me in order to not see the person’s comment.

I have no respect for COWARDS.

A great breakdown below, but I do have a criticism, as I am showing anomalies in this article that CANNOT be explained by a missile! How do people miss this?

Did I NOT make myself clear enough?

Here is AaronKM's reply to the coward;

On a related note and not to be rude but you might consider withholding your thoughts about others and assertions on who knows and doesn't know what until looking into the principles of flight and aerodynamics.

Using science alone and nothing else, the idea that a commercial jetliner could even successfully fy into the pentagon, or any structure, just feet off the ground, is not possible.

I've noted the basic mathematical calculations for speeds, minimum required speeds, and distances elsewhere here on the platform but in short, the minimum airspeed required to sustain flight for 757-200 would never have been accommodated by distance from any direction up to the pentagon without destroying numerous obstacles which , in turn, would have destroyed the aircraft and its ability to sustain flight before hitting the pentagon. It just would not be possible.

But, even if the AA jetliner had been able to reach the pentagon, avoiding all obstructions, it still would have been faced with the concept of "ground effect".

Cleary, aircraft of all designs and sizes are built to best manoeuvre when airborne.

In fact, most aircraft are quite clumsy on the ground and require use of propeller, or jet power, to initiate different manoeuvres on the ground. An aircraft's airfoils are the enabling surfaces that allow for flight.

All aircraft are subject to "ground effect" when landing and all pilots are knowledgeable and trained in how to avoid and how ro manage this factually-sound phenomenon of flight in aerodynamics.

I can best described "ground effect" in this way: have you ever been on a flight that, just before touching down to land, you experience the sensation of hitting a bubble in which the aircraft floats for a distance further down the runway before actually touching down?

That is "ground effect".

The aircraft is travelling at a speed just high enough that it doesn't overcome this effect and wants to continue flying because of the airflow over its flight surfaces, or airfoils.

All aircraft want to fly, by their very nature in build, and given the required speeds and wind velocity, will do so. With this in mind, considering a half-full 757-200 of passengers and total payload, even a many-years-long, seasoned airline pilot would find it impossible to descend to such a low altitude, just feet off of the ground and at such a speed, without the phenomenon of "ground effect' forcing the aircraft upwards and away from the ground.

A loaded 757-200 airliner could not do this at 300, 400, or 500 mph ground speed. It just isn't possible.

Both "ground effect" and required distance in approach to the pentagon would have prevented a 757-200 from such a strike. And I didn't even go into aircraft sink rate which, too, would have contributed to the impossibility of a 757-200 striking the pentagon.

There are just too many scientifically-sound and well-grounded facts that would have made this implausible.

I am not versed or informed in military technologies but what I do know is that missiles are highly agile and well-capable of navigational manoeuvring when airborne at high speeds which make a missile attack the most plausible candidate for the pentagon strike.

Whether it was fired from a warship out at sea, or from a source in low earth orbit, I do not know.

But I do know that no 757-200 could have done this.

Had the strike been at an angle coming from skyward, I can see the possibility of an airliner doing this. But it wasn't.

This was a strike directly to the side of the pentagon. And a 757 couldn't do that.

In fact, a pilot trying to force an aircraft's controls to overcome "ground effect " at those speeds would likely cause a disintegration of the aircraft due to exerting the controls beyond their allowable tolerances.

Once the aircraft's tail, horizontal and vertical stabilizers, rudder, and trim had broken away, it would not have happened at all like this. Like they say: trust the science!

And these are just sound facts in aerodynamics and the principles of flight that can't be overcome or avoided.

Topics to research: Aerodynamics Principles of flight Ground effect Aircraft sink rate Minimum airspeeds Maximum airfoil tolerances 757-200 specifications.

I hope that this adds to your understanding.

yeah I think anyone was common sense at this point with 100% discount the media rhetoric and the historical bullshit regarding the Pentagon strike
