Mr. Specter. And where were you positioned on most of the occasions at the time of the onsite tests?

Mr. Shaneyfelt. For the first portion of them, I was at the car in the street, and at the position of Mr. Zapruder, the position from which he took his pictures.

Mr. Specter. What communications were available, if any, among the participants at the various locations heretofore described?

Mr. Shaneyfelt. We had radio contact between all points.

Mr. Specter. What was the starting position of the car at the most easterly position on Elm Street, immediately after turning off Houston Street?

Mr. Shaneyfelt. The first position we established that morning was frame 161.

Mr. Specter. Was there not a position established prior in sequence to frame 161, specifically that designated as position A?

Mr. Shaneyfelt. That was actually established later. But the first one to be actually located was 161. And we went back later and positioned point A.

Mr. Specter. Well, let's start with the position which is the most easterly point on Elm Street, which I believe would be position A, would it not?

Mr. Shaneyfelt. Yes.
