Fl. 175's Speed: Fairbanks [290+ mph] or Fox [540 + mph]?

Another "Plane" Fact : Contradictory Video Plane Speeds:

 The pre- strike plane speed  for Fl. 175 that I previously calculated via the Fox 5 footage as being 540+ mph , is directly contradicted by the Evan Fairbanks "amateur"footage - which shows a speed of either 148 mph, 296 mph., or 591 mph. depending on the claimed frame speed of the camera purportedly used :-) .

That previous post established the fact that at a video speed of 30 frames per second, the Fox 5 network footage showing Fl.175's alleged flight and collision with WTC2 reveals an [altogether physically impossible for plane] air speed of 540 +mph. as calculated frame to frame.

[N.B. "official " plane speed was/is 520 knots, or 598  mph :-) ].

A 9/11 Video "Evidence" Fact: For Plane Speed Calculations, There Are Only Two Useful Video Sequences

There are only two Fl.175 flight/impact videos that I am aware of with sufficient camera/ viewer perspective of close to 90 degree [i.e. close to 90 degrees perpendicular to the planes path] that allow for a reasonably accurate calculation of frame to frame plane speed .

These two sequences are:

1]: The original Fox 5 national TV network broadcast sequence, as examined in my previous post :

Speed Check

So, in order to double check on the plane speed I have calculated as being 540+mph in the Fox 5 sequence by measuring distance travelled per frame, at an assumed 30 frames per sec. camera speed, I then used the   "AIR VERSUS. SKYSCRAPER" analysis of the Fairbanks sequence, which handily slows the sequence down to reveal individual frames of that sequence:

                    
Plane Speed is Only 296 mph in Fairbanks Sequence?

If we ignore the main purpose of the Killtown analysis , and instead just concentrate on the number of frames the plane image takes to travel its own length, it will be seen that Killtown's frame by frame analysis of the Fairbanks sequence reveals the plane taking 11 frames to travel its own length:

                        

Plane Length= 159 ft.  


Fairbanks Camera's Frame to Frame Speed ? 

The frame to frame speed of the camera used for the Fox5 sequence was apparently 30 frames per second.

I did a superficial search for technical details of the Fairbanks sequence, but drew a blank for frame to frame speed, so I've done my plane speed calculations using three different, most common speeds.

From what I understand, these most common frame to frame speeds are:

1] 15 frames per second

2] 30 frames per second [the industry standard, even in 2016 , as far as I'm aware]

3] 60 frames per second [n.b. I'm not sure if this camera speed was even available in 2001, but included it anyway].

Plane Speed =14.45 Ft. Per Frame

If the plane takes 11 frames to travel 159 ft, it travels 14.45 ft per frame.

Therefor:

1] at 15 frames per sec.: 14.45 ft per frame =216 ft per sec= 13,009 ft. per minute=780,545 ft. per hour:

148 mph

2] at 30 frames per sec. , 14.45 ft per frame = 434 ft per sec= 26,010 ft. per minute, = 1,560,600 ft. per hour:

= 296 mph.

3] at 60 frames per sec., 14.45 ft per frame = 867 ft per sec= 52,020 ft. per minute = 3,121,200 ft. per hour :

591 mph. 


Impossibly Slow, Or Impossibly Fast- Or, Both Fake? 

So there you have it , dear reader, according to the Evan Fairbanks video sequence Fl.175 was either traveling at an impossibly slow [to do what it next supposedly did] 148 mph, [at 15 frames per sec.]contradicting the Fox 5 plane speed of 540+ mph, and the official speed of 598 mph.

Or, an impossibly slow [to do what it next supposedly did] 296 mph,[ at 30 frames per sec.] once more contradicting the Fox5 plane speed of 540+ mph., and the official speed of 598 mph.

or.....

An impossibly fast 591 mph,[ at 60 frames per second, if that camera speed was available in 2001],  which was/is just as impossibly fast as the Fox5 plane speed of "only" 540+ mph [and  just as impossible as the official speed of 598 mph.]

Assume 30 Frames Per Second for Fairbanks Video?

If I assume that the Fairbanks video was shot at the same camera speed as the Fox5 sequence,[ a not unreasonable assumption, I believe], then the Fairbanks video, with its airspeed of 296 mph., directly contradicts the Fox5 sequence, which shows an airspeed of 540+  mph.

Question:

So Who do You Believe: 11 Frames Or, 6 Frames For Plane To Travel It's Own Length ? 

If we assume a camera speed of 30 frames per sec. for , the Fairbanks video shows Fl.175 traveling its own length in almost twice the number of frames as it takes in the Fox 5 sequence. :-) .

And, don't fergit, as the Pilots For 9/11 Truth video clearly demonstrates:


                                
                                       https://www.youtube.com/watch?v=Rs5RQ_5nu4k


... that at anywhere near the official collision speed of  598 mph., [ or even at Fox 5's  revealed speed of 540 mph], or even at  "only" 500 mph........

 at that altitude [1000 ft. and below], the plane would have simply broken apart pre-strike due to the forces exerted on it by the 4x denser [than at 35,000 ft.], air mass.

And, from what I understand [as a non-expert in these matters] - even at 296 mph [ i.e the recorded speed of the E. Fairbanks video, assuming 30 frames per sec.], the plane would still not have been able to endure the massive forces acting on it via 4x air density, descent, and turning maneuvers , and would have therefor broken up, long before any attempted building strike.

Conclusions? 

So, based only on the plane speed issue [i.e. excluding any/all other technical and physical impossibilities shown in either video] :

1]: either the Fox5 sequence is genuine, and the Fairbanks sequence is a fake.

Or,

[2]: the Fairbanks sequence is genuine, and the Fox sequence is a fake.

Or,

[3]: [ horror of horrors], they are both [bad] fakes.

Or,

4] They are both genuine, because you are out of your tiny mind :-) [ get help]

The 9/11 Scam For Beginners- Fox 5 Plane Speed = 540 mph!

[Due to lazy research, where I mistakenly used an average 757/767 plane length of 178 ft. to make my original plane speed calculations, as pointed out by "CriticalMass" at Cluesforum , {thankyou,thankyou CM}, this post has been re-edited and updated on 10/28/15, with "new and improved"  plane speed calculations ]

                                      https://www.youtube.com/watch?v=Rs5RQ_5nu4k


The 9/11 Scam For Beginners: Real World Plane Speeds

Fact: the official strike speed of Fl. 175[2nd plane] into WTC2 was 520 knots, which is 598 mph.

However the maximum speed of  a Boeing 767-200 is stated as being 567 mph. at 35,000 ft [where the air is 1/4 of the density it is at 1000 ft.] :





Meaning that at anywhere near the altitude of 1000 ft. [ the approximate official F. 175 strike altitude on WTC2] , where the air is 4 times denser, an airspeed of anything like 598 mph would be physically impossible for  a  767 jetliner.

Why?


As this Pilots For 9/11 Truth video demonstrates:



https://www.youtube.com/watch?v=Rs5RQ_5nu4k


.... at that speed [598 mph] at that altitude,[1000 ft.],  the plane would have simply broken apart pre-strike due to the larger than designed for forces exerted on it by the 4x denser [than at 35,000 ft.], air mass.


Therefor, any "official" 9/11 video that showed a frame to frame plane image speed of anything like 500+  mph must be fraudulent in some way, right ?


Exhibit A: Original "Live" Network Footage [as archived on line]


So what if a "big time" US network had an original "live"sequence in its official archives on line showing a frame to frame plane speed close to 550 mph?:


Here is the relevant [much shorter] part of the same Fox broadcast, specifically showing the 2nd alleged plane hit [WTC2],  on Youtube:



https://www.youtube.com/watch?v=n-xg-Re4sbg


Wouldn't that [ frame to frame plane speed of close to 550 mph] make  this sequence er, "untrustworthy"?

 [To put it mildly :- ) ]


Here is my evidence that the famous Fox5 live sequence showing Fl. 175's alleged collision with WTC2, as supposedly filmed by a helicopter, shows an impossible plane approach speed [of around 540 mph. ]


Calculations:


In order to calculate frame to frame speed of the plane, we would need to know 3 important facts:

1] Length of plane.


2] the number of frames the plane takes to travel its own length.


3] the number of frames per second of the camera.


Knowing these 3 facts we could then calculate the planes approximate speed/mph. on film.

1]  Plane length- 159 ft.

According to Wikipedia Fl. 175 was 159 ft. long

2] Number of Frames Plane Takes To Travel Own Length?

This was fairly easy to establish via this online frame by frame analysis: http://www.911conspiracy.tv/chopper5_HQ_slideshow.html

Here are my 2 screen shots from the above site , starting at frame 372, with my red circle circling the nose of Fl.175 as it first enters the screen from right to left:


[ You might need to click on/enlarge this image to clearly see the plane nose I have circled in red]


Then I simply clicked the "next" button at the website to advance the view one frame at a time, until the plane image was fully in view.

 I count 6 frames before the plane image is fully in view at frame 378:



So now we can see that the plane travels its own length, 159 ft. in 6 video frames.

3] Speed of Frames Per Sec For Camera Used?

Now, we need to know the frame speed of the camera in question in order to calculate the plane speed per frame.

According to my sources, there were two frame speeds for video professionals available back in 2001, 15 frames per sec. and 30 frames per sec.

The Fox 5 sequence is apparently at 30 frames per sec.

Plane Speed Per Frame = 26.5 ft.

If the plane travels around 159 feet in 6 frames, then it is traveling at a speed of 26.5 feet per frame. [159 divided by 6= 26.5].

@30 frames Per Second

At an assumed camera speed of 30 frames per sec for a plane 159 ft long, that is 795 ft feet per sec., [26.5 x30]; which is 47,700 feet per minute [795 x 60]; which is 2,862,000 ft per hour. [47,700 x 60].

Fox Plane Speed = 542 mph ?

There are 5,280 ft. per mile, so dividing 2,862,000ft. [i.e the distance the plane would travel in 1 hour, expressed in feet], by 5,280 [the number of feet per mile] gives me a plane speed of around 542 mph.

Now, an airspeed of 542 mph at 1000 ft. altitude is no more technically feasible than is the officially claimed pre-strike speed for Fl. 175 of 598 mph - that speed  has already been demonstrated to be technically impossible in the "Pilot's For 9/11 Truth " video linked to above.
