https://drive.google.com/file/d/0BwrExtVD005OWWw0cWdZVVlMVWc/view?usp=sharing Using the magic angle and applying it to the elev (6th floor window sill) of shot #2 and z273 previously plotted, there is a 1ft difference in elevation. The base difference between them is 3.1ft You should know by now that a 3.13degree slope equals a 1ft vertical/18.3ft horizontal distance ratio. 18.3ft -3.1ft = 15.2ft There are two main aspects of this assassination that involve15.2ft

Michael W. excerpt: "That the angles of the road in the reports need to be corrected."

If I was trying to support the lone gunman/6th floor shooter scenario, melding multiple shooters/shots, you can sure bet my ballistics results would support that location. Common location, common/magic angle. If you move back to shot#2, it is listed as elevation 419.07, the height to the 6th floor window sill is 71.83ft (490.9-419.07). https://drive.google.com/file/d/0BwrExtVD005OaURLQUlHa0ZYM1U/view?usp=sharing From that location, using the magic angle of 17.725 degrees, the base distance to the 6th floor SE window = 224.73ft Previously, Chris had asked me what the angle was from z273 to the snipers nest, and I responded with this: http://educationforum.ipbhost.com/index.php?/topic/9975-splice-in-tina-towner-film/&do=findComment&comment=352849

And therein lies your problem. This is what you comprehended and concluded from what I've just presented?

Let's connect that "pivot" angle of 17deg43min30sec from shots 2+3 to the magic bullet. That's the same angle that was used for the magic bullet before the street slope was added into the equation. Amazing that the "pivot" angle was derived using an average angle spanning 15 frames. There is no magic bullet, but there sure is a magic angle. https://drive.google.com/file/d/0BwrExtVD005ONUtUSGVkVFA0d00/view?usp=sharing

If you want to confirm the street angle shenanigan, look no further than the plat (upper-left) where the two distance span measurements are entered (28+24.5) = 52.5ft. At the bottom, those same calculations as the previous graphic will yield a base distance of 52.72ft. https://drive.google.com/file/d/0BwrExtVD005OOWNhYmZsREcyTm8/view?usp=sharing

https://drive.google.com/file/d/0BwrExtVD005OR0dvMnlEUlQ3UVE/view?usp=sharing Thank you David H and Michael C. This is somewhat complicated to explain, but I'll try to make it as easy as possible. The early determination of shot locations were designated on the SS plat of Dec5,1963 along with the FBI revision in Feb 1964. They were labeled as Shot 1,2,3 but what they didn't label with a number (say 4) is the shot at extant z313. I'll only deal with the shots labeled 2,3 to begin with. The plat is on top and the calculations for those two shots below. In the upper left hand corner is the description of the angle that was added to the "pivot" location. Since there were two determinations of the street angle, 3deg8min(3.13degrees) and 3deg9min(3.15degrees), I used the final determined angle (Plat of May 1964) of 3.13degrees. The shot labeled #3 is the location I have previously described as occurring down near Altgens position. The plat dimensions above match the calculations below for the triangles formed in shot 2 and 3. The only difference between shot 2 and 3 is the angle of 3.13degrees (14.595-17.725) which is described as the street grade. 17deg43min30sec = 17.725 degrees

George, 19degrees26min was created by using a base measurement from zframe 273 to the corner of the County Records Building (256.25ft), plus the height of the building (80ft), plus the elev change from those two points(9.94ft) The height of the 6th floor TSBD southeast window sill was measured at 60.7ft high. CE884 measurements use that height(60.7ft), plus the elev change from the building base directly below, out to the particular spot on Elm St, plus the height of the rifle end above the window sill to determine the angle of a location 3.27ft above the ground.

Use the (angle given by the WC as the true angle and County Records Building height along with the elev change 89.94ft) and start from there. From the true angle comes the re-creation. For instance: The 3.27ft JFK head height above pavement when used in conjunction with 17deg48min will yield a difference of 10.24ft which is the distance they moved the Time-Life determined shot @ extant 207 further West down Elm St. to Station# 3+81.3. https://drive.google.com/file/d/0BwrExtVD005OVnA4aW83WHhVUTQ/view?usp=sharing

George, 17deg48min30sec is the trajectory from the County Records Building rooftop. Kiddy-corner from the 6th floor TSBD. 19deg26min = frame 235 from the Southeast 6th floor, at least according to CE884. https://drive.google.com/file/d/0BwrExtVD005OcVphUlV6cHluMFE/view?usp=sharing

Roger, You would have to provide a frame number (math starts from there) that you think would work for a SW corner shooter. Here is a view from that window. https://drive.google.com/file/d/0BwrExtVD005ObHhOS1dmaXFSbTA/view?usp=sharing

JFK gets a hair buzz, simultaneous to Connally getting shot in the back. https://drive.google.com/file/d/0BwrExtVD005ONFJTa3dWRHBjUFk/view?usp=sharing

The last remaining piece needed, which is provided by the WC, was the correct downward angle. That would be 17degrees43min. This helps to explain other adjustments made along the way, creating the parallel scenario. https://drive.google.com/file/d/0BwrExtVD005OMVJmZmVoY0RwWDQ/view?usp=sharing

btw, JFK's position using the lamp-post at z272 plots at Station# 4+35.31 or 30ft.2 short of Station# 4+65.3 = z313

If you refer back to this post: http://educationforum.ipbhost.com/index.php?/topic/9975-splice-in-tina-towner-film/&do=findComment&comment=351165 Myers subtracted 1.8 seconds to the equation by increasing the frame rate of Towner's camera. Actually it would be 1.83 seconds as the total difference of(167and100 frames) split, when each applied to CE884 @ 30ft gives us our 2.24 and 3.74mph match. 1.83 seconds x 18.3fps = 33.48 frames = 34 whole frames The difference in where Shaw said Connally was hit and the real shot being fired is 34 frames or z236-z270. So you can surely count on at least 34 frames being removed near/after the real Connally back shot.

btw, When I referred to the Itek study and supplied the frame analysis within the report, I never divulged it was a study on the Nix film. Some of you familiar with the report would have known. So how is it that Myers multi-film sync study starts with Nix at z291, yet the Itek study went back 28 frames from z313 or z285. Sounds like 2 different films and missing frames to me. Frame counting coming.

Wow. Coincidentally, Muchmore starts filming the assassination sequence at z272. Nix at z291. Selective splicing!!!! Think some frames were pulled? Myers sync below: https://drive.google.com/file/d/0BwrExtVD005ONUlvWUhlS1lhdjg/view?usp=sharing https://drive.google.com/file/d/0BwrExtVD005OVFNOcjB0dVVibU0/view?usp=sharing

Mr. WITT. Let me go back a minute. As I was moving forward I apparently had this umbrella in front of me for some few steps. Whereas other people I understand saw the President shot and his movements; I did not see this because of this thing in front of me, The next thing I saw after I saw the car coming down the street, down the hill to my left, the car was just about at a position like this [indicating] at this angle here. At this time there was the car stopping, the screeching of tires, the jamming on of brakes, motorcycle patrolman right there beside one of the cars. One car ran upon the President's car and a man jumped off and jumped on the back. These were the scenes that unfolded as I reached the point to where I was seeing things. Since the public didn't see the zfilm until Groden in 1995, and Witt testified in 1979 HSCA, I find his description of the events quite compelling. After Connally gets shot in the back, Greer hits the brakes and the car appears to stop (more than likely, slowed down tremendously). Eventually it will be moving at 3.74mph. Brehm (after Connally shot) estimates in this transition period the limo moved 10-12ft. BREHM expressed his opinion that between the first and third shots, the President's car only seemed to move 10 or 12 feet. It seemed to him that the automobile almost came to a halt after the first shot, but of this he is not certain. After the third shot, the car in which the President was riding increased its speed and went under the freeway overpass and out of his sight. Added on edit: Hickey wasn't the only one to see the hair rise. When the President's automobile was very close to him and he could see the President's face very well, the President was seated, but was leaning forward when he stiffened perceptibly at the same instant what appeared to be a rifle shot sounded. According to BREHM, the President seemed do to stiffen and come to a pause when another shot sounded and the President appeared to be badly hit in the head. BREHM said when the President was hit by the second shot, he could notice the President's hair fly up, and then roll over to his side, as Mrs. KENNEDY was apparently pulling him in that direction.

The first frame I see JFK's hair fly is z273. Nellie responds by whipping her head around to view JFK. Connally responds to being hit by pushing back towards Nellie. Jackie is a little later than Nellie in her response. Greer and Kellerman also turn their heads forward quite quickly.

The limo was traveling at 11.2 mph(using landmarks 9 frames@8.1ft) from z263-z272 (as the shot occurred). 18.3/9=2.0333.. x 8.1 = 16.47ft per sec/1.47(1mph) =11.2mph Using 2165ft (given testimony) per sec as a bullet speed (not saying it was the MC used) a slope distance of 271.57ft would take 2.4 zframes to hit it's target. The shooter pulled the trigger at z270, it just missed JFK's head (hair flew up) Hickey saw it, and it drilled Connally through the back. That shot was intended to blow JFK's head off, not hit Connally. Slight bend in the road/Slightly high on the aim. If you look at the Connally stabilization closely, you'll see JFK's hair movement. I have a much better quality looped version I'll supply, eventually. https://drive.google.com/file/d/0BwrExtVD005ONFJTa3dWRHBjUFk/view?usp=sharing More coming.

https://drive.google.com/file/d/0BwrExtVD005OeExpWWlvbU9lT2s/view?usp=sharing The base distance from z273 to County Records Building Annex corner (Photo)= 256.25ft The rooftop = 80ft. The elev change = 430-420.06 = 9.94ft The angle needed for this shot to the street is 19.34 degrees or 19 degrees 20.4min The parallel scenario set forth by the WC (6th floor SE window) is thru Shaw's testimony who states somewhere around z236. If one will look back at CE884 data for z235, the angle set is 19degrees 26min. The angle change in CE884 for z235-z240 = 25 minutes or 5 minutes per frame. So z235 (19deg 26min)- 5min (z236) = 19deg21min which is a match. Some more coming.

Thank you Chris + David for your questions and insights. They have allowed the "process of elimination" sequence to answer them. Explanation to follow.

The 6th floor window sill is elevation 490.9 z273 = elevation 420.06 Difference = 70.84ft Base measurement to 6th floor = 224.3ft Once again, this is measuring to the street. Adjust 1 degree = 3.27ft vertical, depending on location of wound. Difference of 25 degrees - 17.53 degrees = 7.47 degrees https://drive.google.com/file/d/0BwrExtVD005OWm1IYlhFeHBVTE0/view?usp=sharing

Thanks Chris, This is what would work for a 25 degree angle. The base distance to the setback roof = 308ft approx. That’s 244ft to the building base and another 64 ft back to the setback. The adjacent Criminal Courts Building (right-side) rooftop for comparison = 120ft The elev change to z273 = 9.94ft. 144ft-9.94ft = 134ft height for setback rooftop. A height of 144ft at a 25 degree angle = 308.8ft base. The shot would have been approx 340.7ft Of course the lateral angle would have to work. https://drive.google.com/file/d/0BwrExtVD005OaEJsN3FUOHN3aE0/view?usp=sharing

Chris, In your opinion, disregarding any math for now: What view among the two provided would align more closely with the LOS (red line 25 degrees). I cloned the white car (red arrows) and moved it closer to where I believe the limo appears in z273. https://drive.google.com/file/d/0BwrExtVD005OeWhfVEh6b1ItTzA/view?usp=sharing
