I like that. Aetherians, or the Aetha, forming the Aethan Federation.  The mortal enemy of Einsteinists.

Unsolved History is history the way it was, Through detailed examination of archeological and forensic evidence, existing photographs, authentic artifacts, and carefully selected interviews from eyewitnesses and experts - events are reconstructed and historical questions are finally answered. Join the investigators of Unsolved History for a final, definitive look at the assassination of President Kennedy in this special, extended episode. After 40 years of heated debates and accusations, the physical evidence that remains from that day in Dallas is all that can be objectively examined. Watch as experts scrutinize film footage and authentic photos taken the day of the assassination for uncovered clues. The alleged assassin's timeline is broken down to the nearest minute to show where he was at the time of the shooting - and whether or not the "accepted" version of Oswald's plot holds true. Listen in on an obscure audio recording that may shed light on the identity of the true triggerman and examine Exhibit #399 - the so-called "magic bullet," the most controversial piece of evidence. It's an in-depth examination of the unanswered questions, conspiracy theories and physical evidence behind the shots that changed history.

Does this show Brennan crouched down next to the wall that he was sitting on?
And possibly a 2nd person (Euins?) is crouched in front of Brennan.
I believed that Brennan & Euins (after the shots) crouched or lay behind the high thick part of that block wall, ie say 14 ft further away than where shown in this photo (not very important).

                    OSWALD'S ACTIONS [& Brennan's actions]. 
I now like the following sequence of actions by Oswald & Brennan, based on Brennan's words.
LHO's are Oswald's actions. [Brennan's actions are in brackets].
The Z numbers are the frame numbers of the Zapruder footage which actually starts at Z133 in the final sequence, running at 18.3 fps.
Z numbers before Z133 are pseudo numbers based on estimates of timings.

Z000 minus a few minutes. [Brennan sees Oswald in the window some minutes before JFK arrives]
Z000 minus a few minutes. [Brennan climbs up & sits on the curved brick wall on the south-west corner of Elm & Houston]
Z002. LHO sees JFK approaching along Houston St.   Click…Click (ejects empty casing)(loads bullet).
Z002. [Brennan watches JFK along Houston St & turning onto Elm St]
Z080. LHO aims rifle at JFK as limo turns onto Elm St.
Z102. LHO fires Shot-1 as the limo straightens.
Z103. The slug ricochets off the overhead signal arm & makes a hole in the floor of the limo (hole found Dec 1963).
Z104. [Brennan hears Shot-1 & thinks it is a backfire or a firecracker][he continues to watch JFK along Elm St]   
Z112. LHO  Click…Click.
Z133.................................... The Zapruder footage 2nd sequence starts at Z133.
Z133. [In the footage we see Brennan sitting on the wall]
Z152. LHO aims. A tree blocks a clean shot.
Z207. [Our last view in the footage of Brennan sitting on the wall][After Z207 Brennan is out of frame]
Z207. [The footage shows that at no time during Z133 to Z207 has Brennan looked up towards Oswald]
Z217. [Brennan's last view of JFK -- koz a shrub now blocks Brennan's view down Elm St]
Z216. LHO fires Shot-2. The slug hits JFK & Connally at Z218 (the magic bullet).
Z218. [Brennan hears Shot-2 & realizes that it was a rifle]
Z225. [Brennan looks up & sees Oswald aiming a rifle at JFK]
Z227. LHO  Click…Click.
Z255. LHO aims. Sees that JFK has been hit.  Decides not to shoot his last bullet (why?).
Z268. LHO stands up & backs away from window, looking at JFK.
Z268. [Brennan sees Oswald stand up & back away & look]
Z280. [Brennan jumps off the wall, & ducks behind a solid section of wall 12 ft away & lays on the grass]
Z313. LHO steps further back from window, still looking, sees agent Hickey shoot JFK in the head.
Z312. [Brennan is laying on grass behind the wall & doesn't hear Hickey's shot(s) starting at Z300-Z312 ]
Z322. LHO walks to the stairs, wiping the rifle, & hides it. There is a 3rd bullet in the rifle. LHO does not pick up his rifle-bag nor the 3 empty casings near the window.
Z400. [Brennan leaves the wall & talks to a cop]
......................................[Brennan heard 2 shots & saw none]
