As you well know, but insist on denying, we don't need any videos to "prove" AA77 hit the Pentagon. Unlike "Truthers", we deal with all of the evidence and that evidence told us AA77 hit the Pentagon.
Steel samples were removed from the site before the NIST investigation began. In the immediate aftermath of Sept. 11, debris was removed rapidly from the site to aid in recovery efforts and facilitate emergency responders’ efforts to work around the site. Once it was removed from the scene, the steel from WTC 7 could not be clearly identified. Unlike the pieces of steel from WTC 1 and WTC 2, which were painted red and contained distinguishing markings, WTC 7 steel did not contain such identifying characteristics
The severe corrosion and subsequent erosion of Sample 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been identified. The rate of corrosion is also unknown. It is possible that this is the result of long-term heating in the ground following the collapse of the buildings. It is also possible that the phenomenon started prior to the collapse and accelerated the weakening of the steel structure. A detailed study into the mechanisms of this phenomenon is needed to determine what risk, if any, is presented to existing steel structures exposed to severe and long-burning fires
One piece Dr. Astaneh-Asl saw was a charred horizontal I-beam from 7 World Trade Center, a 47-story skyscraper that collapsed from fire eight hours after the attacks. The beam, so named because its cross-section looks like a capital I, had clearly endured searing temperatures. Parts of the flat top of the I, once five-eighths of an inch thick, had vaporized.
Various metals (most notably iron and lead) were melted during the WTC event, producing spherical metallic particles" Many of the materials, such as lead, cadmium, mercury, and various organic compounds, vaporized and then condensed during the WTC event

Sorry, Kryties, you'll be wanting to retract your statement as soon as you sit down and think how completely irrational and embarrassing your statement is to you.
This is the classic problem with 9/11 "Truthers" who have been led down the garden path by their fellow "Truthers" into actually believing, against ALL reason and logic, that we do not have the evidence already to KNOW that AA77 hit the Pentagon.
When will you ever come out of the fog and understand that no one in the world needs ANY video to KNOW that all of the evidence we have had since 9/11 demonstrates conclusively that AA77 hit the Pentagon? How could you NOT know that, Kryties?

You asked: "I'm asking where is the long smoke trail after the plane crashed?"
Answer: Witnesses claimed that they heard a large boom followed by a mushroom cloud which doesn't follow a regular plane crash to begin with. It more closely resembles a bomb going off, but you are not even focusing on this. You are asking why the plane didn't produce this smoke chimney effect, well, the plane did have 8 miles to come apart right? One engine over here, one engine over there. One seat over here and a couple of miles later, one seat over there.
Next you make a claim: "If a 757 crashed even in remote New Baltimore, the smoke trail that would arise after it crashed would be seen for miles and miles."
Oh ok, nevermind the fact that it had 8 miles to come completely apart and have nothing but shrapnel to hit the ground with. But wait a second everyone, according to ATH911 a plane simply must always create a long smoke trail to be seen for miles even if they've possibly been hit by missiles that are well known to blow flying pressurized planes to pieces.

On question number 6 let me say something.
The collapse of building 7 takes place in two phases.
You can´t consider the time of the collapse only the final part that we all have seen on short videos.
There´s a video that clearly shows the collapse of a part of the building first, referred to as the Penthouse.
And some time passes and then the collapse of the whole (rest of) thing takes place.
But the thing is, the building was falling appart or collapsing from within for some seconds before the final demise.
So, it is incorrect to time the collapse only for the part that shows the whole building falling and not from the time the Penthouse falls.

NIST could not find the WTC 7 steel at all, so they could not study this further.

That's just the trick NIST used to add time where the exterior of the building was not moving.
When the exterior starts moving, it accelerates at 9.8m/s^2 or 32.2 ft/s^2 to within a very small margin, as shown by NIST themselves. There is no hiding this fact. Well, besides sandwiching it between two irrelevant "phases" and pretending it's ok now.
Accelerating at the rate of gravity (at ANY point in time) means no PE/KE used to collapse the building, ie 0 energy going to collapse the building, meaning it (a) isn't collapsing, or (b) some other source of energy is doing the "collapsing."
NIST has reversed its earlier denial of freefall and acknowledged a period of freefall comparable to this analysis in their final report on WTC7 released in November 2008. They did their own measurement with a point near the center of the roof line and came up with an acceleration of 9.81 for approximately 2.25 sec. Their report did not, however, face the consequences of this acknowledgment: that ALL RESISTANCE was instantaneously removed across the width of the building, supporting pre-planted explosives as the cause of the collapse.
Note that:
--He acknowledges that freefall can only occur if there is no structure under the falling section of the building.
--He acknowledges that their structural modeling predicts a fall slower than freefall.
--He acknowledges that there was structural resistance in this particular case.
--He acknowledges that there was a sequence of failures that had to take place and that this process was not instantaneous.

More smoke and mirrors. We do NOT know for a fact that AA77 hit the Pentagon, if we did then why are people still asking questions about it?
You seem to be carrying this argument as if your side has already been proven, a fact that this very thread and it's opening post disproves.
As far as I, and MANY other people are concerned, if AA77 hit the Pentagon, why is there any need to withhold video evidence? Shouldn't video proof be EXACTLY what you guys are after to prove your case? Or is it that you are not sure of what the tapes will show?
Emergency Response, Rescue Operations, Firefighting, Secondary Explosions
Conspiracists are afraid to have their fantasies destroyed, so they scrupulously avoid contacting the hundreds of Pentagon 9/11 first responders and the over 8,000 people who worked on rescue, recovery, evidence collection, building stabilization, and security in the days after 9/11. These are just some of the organizations whose members worked on the scene:

6) What allowed WTC7 to accelerate vertically at the rate of free-fall in a vacuum?
Please substantiate the free fall in a vaccum claim.
