The attachment is from Tom Purvis.

The term "flat-line distance" refers to the distance from the (bottom of the TSBD snipers nest, out to the designated point of bullet impact on Elm St).

More from Tom Purvis regarding shot#1.





This flat-line distance equals JFK's position in extant zframe 207. If you look closely, it was labeled very lightly on the 1963SS/1964FBI plat.

Approx 123ft. from Zapruder is extant Z207.
