-------------------------------------------------------THE AIRPORTS

19 alleged terrorists (to be referred just as terrorists from now on) were able to avoid hundreds of airport CCTVs, except 3.

Of those 3, one of the recordings (which will be named Dulles from now on) that was only released in 2004 poses a serious problem:

At least until the date of the 9/11, all of the CCTVs available (including the Pentagons') only recorded at 1-5FPS and had timestamps while the Dulles was recording at +12FPS(if I am not mistaken) and has no timestamp.

The airports, which the terrorists used, have hundreds of CCTVs that cover the entrances and all of the public areas, yet only 1 camera from 2 airports (Dulles and Portland, Maine) were able to capture 6 of the 19 terrorists. The airplane victims were also never captured by the airport CCTVs. In contrast, here is the constant tracking via CCTV of the navy yard shooting using all the CCTVs that captured the shooter outside and inside the building.

Somehow the Logan airport failed to record a single victim and/or terrorist.

--------------------------------------------------------THE HIJACKS

Every pilot and co-pilot is instructed with transponder squawk codes, one of them -7500- is the code for hijacking and it takes 3s to input and send.

Despite having 4 pilots and 4 co-pilots, not one of them sent out the 3s squawk as they were instructed to. The alleged Flight11's FDR shows that the airplane was too high to have struck the lamp posts.

Todd Beamer, one of Flight93's passenger, described the hijack occuring as he was speaking (at 9:43 AM) when in fact this event had already happened ~20 minutes earlier.

--------------------------------------------------------THE CRASHES

-------------------------THE PENNSYLVANIA---------------------------

Despite the entire airplane allegedly plunged into the ground, one of the engines jumped to a considerable distance from the crash site. This engine was attached to the same airplane as the other one, diving at the same speed as the other one and hitting the same ground as the other one, yet one of the engines was buried and the other landed far away for no reason.

The engine that was buried under the ground was compressed along it's length under ~3 and half feet of dirt. This engine had a clam shell of considerable proportions, but for some reason not one part of that shell is present in the previously linked photo of the engine.

There were debris found at such a distance from the impact point of the airplane that it could not have been covered from its explosion, this path of debris suggests that the airplane was actually flying on the opposite direction and not the one officially told. This also fits Val MacClatchey's testimony of the plane path.

Val MacClatchey's famous photo poses a serious problem, it displays a mushroom cloud that is consistent with an explosion and not with a jet crash. When an airplane crashes it produces a long column of smoke, not just a mushroom cloud. The lack of typical airplane crash aftermath smoke has also been confirmed by another witness.

In contrast with Flight 93, here is an airplane crash of a Boeing 737-200 of 17,November 2013 that nose dived in 70º and still had plenty of easily identifiable airplane parts and both engines were found in the same location.

Here you can see more airplane crashes comparisons with Flight 93 and see how unique Flight 93 was. http://killtown.911review.org/flight93/crash-comparisons.html

----------------------------------------------------------THE CALLS

There are 2 calls that contradict the offical version of events; the before mentioned Todd Beamer call and Jeremy Glick's.

Todd Beamer:

Flight 93 hijack occured at 9:28

Todd Beamer's call describes the hijack about to happen at 9:43

Flight 93 crashed at 10:03

Todd Beamer's call made with an airphone last for 3925 seconds. It last 45 minutes after the plane had already crashed.

Lisa Jefferson also confirms that the call was not lost: "We didn’t lose a connection because there’s a different sound that you use. It’s a squealing sound when you lose a connection. I never lost connection, but it just went silent."

Jeremy Glick:

Call starts at 9:37

Flight 93 crashes at 10:03

Call lasts for 7565 seconds, placing the end of the call at 11:41. It last for 1 hour and ~38 minutes after the plane had already crashed.

These calls were made from the airplane's airphone destined to two different interfaces: One was to the GTE's assistant landline telephone, the other was to a cellphone.

These calls could not have remained connected by a system mistake because airphones charge per time, the system was built to only count the time the client is connected in order to avoid overcharging him by allowing calls to "stay connected" when they were not. The fact that they also disconnected at different times rules out any possible system fault which, if possible, would at best disconnect both calls at the same time since they would have "disconnected" at the same time, the time of the crash.

The ACARS data also corroborates the above, seen that the only possible explanation for the calls to remain connected after the airplane crashed is that the airplane from where the calls came from never crashed in the first place.

--------------------------------------------THE TOWERS' COLLAPSES

-------------------------SOUTH TOWER--------------------------------

The section above the airplane impact zone tilted and then fell vertically, violating Newton's First Law of Motion in which a body in motion (rotation in this case) tends to stay in motion unless acted on by an outside force. In this case this was the expected movement of the top if it was simply collapsing.

Despite the fact that the top section tilted and was only ~30%(33floors) of the building it was still capable of destroying the remaining ~69%(76 floors) completely, directly violating Newton's third law.

-------------------------NORTH TOWER--------------------------------

A problem with this collapse is that despite the fact that the top section fell vertically and almost symetrically, it can be clearly identified a concentrated destruction almost as fast as the debris fall occuring on the right face of the building.

Sharing the exact same result as the South Tower, the North tower also violates Newton's third law by an even larger margin. The top section was only 15.45%(17 floors) destroying the intact 93% 83% (92 floors).

According to NIST, WTC1 fell only 28% longer than pure free-fall:

"The upper section of the building then collapsed onto the floors below, within 12s, the collapse of WTC 1 had left nothing but rubble."

NIST file NCSTAR1 section 2.9

If it was free fall it would have been 9.32s without air resistance, meaning that -according to NIST- all floors provided a resistance that add up to 2.77s (12s - 9.32s).

Below the collapse area there were 95 floors.

2.77s / 95 floors = each floor being destroyed in 0.029s

29/1000ths of a second.

According to NIST, each floor -composed by concrete and steel- was being destroyed as fast as the impact between a stick and a cue ball.

Despite the top being only ~16% of the building (weaker and lighter), the result was still a perfect vertical gravity assisted downfall destruction of the remaining 93% 83% perfectly intact structure (stronger as well) defying yet again another law of physics -Newton's third law- in which a smaller and weaker body cannot destroy a bigger and stronger body.

For example: for every floor of the 93% 83% destroyed another floor of the 16% has to be destroyed. If Newton's third law had been respected, the building would be standing with ~75 floors, not 0.

-------------------------TOWER SEVEN--------------------------------

Building 7 was hit by the debris from one of the collapses which caused fires and facade damage, one easily identified top to bottom gash.

Despite the presence of large quantities of smoke, there was never discovered any floor completely engulfed by fire, only partial fires and only on a few floors. The presence of soot in the windows are the indicator of fires that were already extinct.

The only fires that last long enough and could be responsible for the building to collapse were only on 3 floors and they were only partial small fires.

For a better comparison on the dimensions of WTC7's small office fires, here you have an example of normal office fires (or just plain office fires) and extreme office fires (or infernos).

By the time that the collapse initiated there were no more fires near the vicinity of the section that was appointed as the collapse failure initiation. This means that the building started the collapse for a reason other than fire.

Despite public belief, the building did in fact collapse with sudden onset of free-fall (18 visible stories in 3.9s), there were no stages. A better explanation is provided below.

http://www.sharpprintinginc.com/911/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=207&MMN_position=616:616

There was also a loud explosion that occurred right before the penthouse collapse. That explosion cannot possibly be from any structure "snapping" or "failing" because you would hear in that same video the rest of the building collapse as well, which you do not. If you cannot hear the entire building collapse then that explosion couldn't possibly be from a column failing.

In contrast with the WTC7 building, here you can see the other buildings that were hit with exponentially bigger forces (hit directly by the towers' debris), some which under larger fires and did not globally collapse:

WTC3, WTC4, WTC5, WTC6, Deutsche bank building

And here are buildings that suffered extreme office fires and did not turn into a pile of ruble:

To end this list I would like to make a question which isn't meant to seek an answer but purely to make you ponder:

If you weren't aware of which buildings collapsed that day; Which one of these two buildings would you say turned into a pile of rubble: WTC5 or WTC7?

PS: For any debunker that tries to answer/debunk the question even though I clearly stated that I am not looking for an answer but to make people ponder:

Remember that NIST has already stated that the structural damage was irrelevant and that the building would still have collapsed without any damage:http://np.reddit.com/r/conspiracy/comments/21ubl5/people_trying_to_debunk_911/cggtw3u.

The argument of pointing out how much smoke there was on the other side is also irrelevant for 1 reason: smoke is not fire. For both pictures I only show the actual fires in both buildings and not the smoke coming out from either one.
