Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Connally was 2 inches taller than Kennedy, so in a regular car, he would have been higher up than Kennedy due to his height. But, in this case, the Presidential seat in back of the limo had the capacity to be elevated. How much was it elevated? That seems to be in question, but Connally guessed 6 inches. Here is his testimony about it to the WC:

Mr. SPECTER. What was the relative height of the Jump seats, Governor, with respect to the seat of the President and Mrs. Kennedy immediately to your rear?

Governor CONNALLY. They were somewhat lower. The back seat of that particular Lincoln limousine, which is a specially designed and built automobile, as you know, for the President of the United States, has an adjustable back seat. It can be lowered or raised. I would say the back seat was approximately 6 inches higher than the jump seats on which Mrs. Connally and I sat.

Mr. SPECTER. Do you know for certain whether or not the movable back seat was elevated at the time?

Governor CONNALLY. No; I could not be sure of it, although I know there were---there was a time or two when he did elevate it, and I think beyond question on most of the ride in San Antonio, Forth Worth, Houston, and Dallas, it was elevated. 

So, how much higher was Kennedy than Connally at the crucial moment? Let's look at it at the crucial moment.

Why don't we think of it in terms of head length? If Kennedy were a head taller, it would work out to about 9 inches. But, he is obviously not a head taller. Is he half a head taller? In that case he would be 4.5 inches taller. 

And remember that that includes everything because we are looking at the actual result here. You can see the slant of the road by looking at the line of the car and seeing how it declines from left to right. 

Just for the fun of it, I drew a line across.

You can see that the top of Connally's head lines up with Kennedy's eyes. On me, that's about 4 inches. And again, that's everything And it happens to be the figure I used in my original calculation. But, if we take it up to 5 inches, it still amounts to only a 7.96 degree angle between Kennedy and Connally- which is much less than the steep angle between Supposed Oswald and Kennedy. Here is Richard Charnin's spreadsheet:

Even taking the largest proposed angle between Kennedy and Connally, 7.96 degrees, it is nowhere near the 20+ degree angle between Supposed Oswald and Kennedy. It's only about half of the 17 degree angle that is sometimes used erroneously.
