Mr. SPECTER. Of the viewer.
Mr. SHANEYFELT. On the upper left-hand side.
Mr. McCLOY. I think you said right.
Mr. SHANEYFELT. The upper left-hand photograph is the photograph from
the--taken from the frame 24 of the Nix film.
The photograph on the right, upper right, is the photograph taken at
the reenactment from the position where Mr. Nix was standing. We then
proceeded over to the point that we had established as the position
of Mrs. Muchmore, and using frame 42, which is a frame in her film
depicting the shot to the head, and using the steps and their relation
to the President and the objects in the background in relation to the
President as shown in this lower left-hand photograph, which is the
Muchmore frame 42, we reestablished, we checked the position we had
placed the car in, based on the Nix photographs, and found that it
conformed and checked out as being in a closely accurate position.
This is the basis used for establishing the position of the car. After
we had established that, through the Nix and Muchmore films, we then
checked it against the Zapruder photograph, which is the second from
the top on the left of Commission Exhibit No. 902, frame 313, which
shows the explosion from the top of the President's head. Just to the
right of that second picture down from the right, is the photograph
made at the reenactment from Zapruder's position.
We know from studying the films that just two or three frames before
frame 313 we can see a little bit of yellow along the curb, and this
checks out because along this area of the photograph from the Zapruder
position of the reenactment is a yellow strip.
Mr. SPECTER. When you say this area you are referring to the yellow
area which appears on the left-hand curb immediately to the rear of the
simulated car?
Mr. SHANEYFELT. That is correct, and this, therefore, checks out this
as being a fairly accurate position for the car in frame 313.
This photograph then, the third down on the left, is a photograph
through the telescope of the rifle of the car positioned in frame 313.
Mr. McCLOY. Would you read off those dimensions from that?
Mr. SHANEYFELT. The dimensions from the surveyor on frame 313 of the
distance from the wound mark on the President's stand-in to station C
is 230.8 feet.
Distance to the rifle in the window is 265.3 feet. The angle to rifle
in window is 15°21´ and this is based on the horizontal.
Distance to the overpass is 260.6 feet, the angle to the overpass is
1°28´.
Mr. SPECTER. What would the angle be considering the adjustment on the
angle of the street?
Mr. SHANEYFELT. It would be less 3° or 12°21´, approximately.
Mr. SPECTER. When you say approximately is that because the adjustment
is somewhat greater than 3°?
Mr. SHANEYFELT. Yes.
Mr. SPECTER. How much is it exactly, if you know?
Mr. SHANEYFELT. It is 3.9. It is almost 4.
Mr. SPECTER. Three degrees nine minutes?
Mr. SHANEYFELT. Three degrees nine minutes, I am sorry.
Mr. DULLES. Would you have to make a similar adjustment to the overpass?
Mr. SHANEYFELT. Yes; because the angle to the overpass is based on the
horizontal. The overpass, you would have to add the 3°9´.
Mr. DULLES. From the overpass, is this an angle up or angle down?
Mr. SHANEYFELT. This is an angle down.
Mr. DULLES. So it is an angle down in both cases?
Mr. SHANEYFELT. That is correct.
Mr. SPECTER. When you say that you are reducing the angle of 15°21´ by
3°9´ to an angle of 12°12´, is that as the shot passes through the body
of the President?
Mr. SHANEYFELT. That is correct. It is at that point.
Mr. SPECTER. How was the speed of the camera ascertained, Mr.
Shaneyfelt?
Mr. SHANEYFELT. We obtained from Mr. Zapruder, Mr. Nix, Mrs. Muchmore;
their cameras for examination, and in the FBI laboratory exposed film
in all three cameras, aiming, focusing the camera on a clock with
a large sweep-second hand. We then ran the camera at the speed and
conditions as described by the people who used the cameras. We ran
through several tests of film, and then after the film was developed it
was studied under magnification, and frames were counted for a period
of 2 to 3 seconds or for the full running time, and averages were taken.
Mr. Zapruder has stated that his camera was fully wound. Most of the
others have stated their cameras were fully wound, so we were able to
more or less eliminate the very slow time that occurs when the cameras
are approximately run down, and all of these things were taken into
consideration and were averaged.
The Zapruder camera was found to run at an average speed of 18.3 frames
per second.
The Nix and Muchmore cameras were both found around 18.5 frames per
second.
Mr. SPECTER. Were you able to ascertain the speed of the Presidential
limousine at the time of the assassination?
Mr. SHANEYFELT. Yes; because we were able to determine the speed of the
camera, and thereby accurately determine the length of time it takes
for a specific number of frames to run through the camera at this 18.3
frames per second, and having located these frame positions in the
street, we took the farthest distance point we had in the Zapruder film
which was frame 161 through frame 313.
This was found to run elapsed time from the film standpoint which runs
at 18.3 frames a second, runs for a total of 8.3 seconds.
This distance is 136.1 feet, and this can be calculated then to 11.2
miles per hour.
Mr. SPECTER. Is that a constant average speed or does that speed
reflect any variations in the movement of the car?
Mr. SHANEYFELT. That is the overall average from 161 to 313. It does
not mean that it was traveling constantly at 11.2, because it was more
than likely going faster in some areas and slightly slower in some
areas. It is only an average speed over the entire run.
Mr. DULLES. Over the entire run between what points?
Mr. SHANEYFELT. Between frame 161 and 313.
Mr. DULLES. Yes; but where, could you place that on that chart, for
example?
Mr. SHANEYFELT. Yes.
Mr. DULLES. And describe the points?
Mr. SHANEYFELT. This is frame 161 which is the frame where they have
just gone under the tree, to frame 313 which is the shot to the head.
So that it is that distance there which is 136.1 feet.
Mr. SPECTER. In referring to those points, will you specify what
exhibit number you are referring to there?
