It really is, me and my colleagues will be laughing about Rahn's assertions of "jet effect" ignoring conservation of momentum to the extent of completely overwhelming the original source of energy to the situation. .....maybe it's a nuclear reaction thing!!!

And even with all of that calculation, Rahn still can not keep track of conservation of momentum, what really constitutes thrust (as opposed to simple fundamental energy transfer between objects in a collision) and which direction that various factors really plays into.

so the shot from the rear facilitated both forward and rearward movement of JFK's head. but just as much it would be impossible for a shot from the front to contribute to either.

"backspatter" -The truly propulsive mechanism of the entry zone (of utterly trivial magnitude and consequence) in operation, that Rahn is so concerned about because he (errantly) asserts that is of over whelming magnitude as he also goes on to errantly assert that it is in effect on the target body in the exit zone of the High Speed Projectile, just as Rahn can not tell which zone is which ........which renders all Rahn-g (Wrong) results.

This a very subjective approach to an attempt to (supposedly) objectively explain a mechanically occurring chain of events ....or is it just explain-like logic in action!!!
> "The momentum of the exiting fragments
meaning "fragments" of the (supposed) 6.5 mm FMJ bullet attributed to Oswald .....BUT WAIT !!!, FMJ bullets are intended to be very resilient and to NOT fragment especially in soft matter like human tissue EVEN IF impact occurs at highest possible /muzzle velocity. And as a specific indication of that high resilience of 6.5 FMJ bullets, the other (magic trajectory) 6.5 mm FMJ bullet of Oswalds found on the stretcher at Parkland hospital which struck Kennedy and Conally was NOT even deformed let alone expanded let alone fragmented. It appears that they vaunted Rahn has given some sign of contradicting himself ( just as Steve Benson did when Steve divulged that Governor Connally who was supposedly shot by the magic bullet did not believe the KEY WCR contention/finding that the same bullet had hit Kennedy and himself /Connally.
https://www.youtube.com/watch?v=-RGZPa8FdbA....unless you want to claim that bullet means nothing because it was planted which will then blow a big hole in the (your) Lone Gun Man theory. The choice is yours. ,

as well, that action would be a fundamental energy transfer from a collision which does NOT produce thrust, especially magic countering thrust on the target object.

even so, poor Jackie goes onto the rear deck lid of the Lincoln Pres Limo to collect fragments of Jack's shattered head, even though the primary fragments went forward according to Rahn

So... the energy transfer of impact that occurred on the head somehow magically acted in the lower area of the body so the action could be made to match the events ? A truly amazing statement coming from a person who made this statement in his foreward. QUOTE And most importantly, they should commit themselves to learning the truth, wherever it lies. UNQUOTE
......so interesting that Con Man Rahn ended up saying that the truth lies.....
how about just following the facts where ever they lead instead of making them "lie"

Said the guy who did a lot of (Mis applied) calculations on bullet energy and conservation of momentum while also ignoring it, AND who also has ZERO empirical data on force /energy of muscle contractions that he then goes on to invoke and depend on ...........when he is not relying on his "jet effect" theory.
From section 8 of Rahn's treatise.
QUOTE
When all is said and done, the plausibility arguments show that a WCC/MC bullet from Oswald's rifle can easily explain the forward snap. That should come as no surprise. They also show that the bullet can easily explain the initial part of the rearward lurch, via the phenomenon commonly known as the "jet effect."
UNQUOTE
In order for the Rahn's invoked (so called) "jet effect" to function/operate to move JFK's head backwards toward the source of the bullet, JFK's head has to become an effective Pressure Containment Vessel, as that effective PCV JFK's head is able to effectively contain HIGH pressure the likes of which are necessary to induce substantial jet thrust needed to make the PCV move very abruptly at the right moment, even though the PCV is pierced at an entry point by a High Speed Projectile / Bullet. With in the confines of the PCV the HSP imparts its very directional Kinetic Energy to the material (brain matter) contained inside the PCV. As the HSP is slowed by the contained material, the HSP's kinetic energy is consumed and converted to potential energy by compressing ......and "oscillating" the contained material. While that dynamic exchange process is going on, the bulk of PCV is temporarily able to somehow completely resist the natural tendency of moving in the same direction that the HSP is traveling. The slowed HSP projectile finally passes through the PCV to where the HSP punctures the wall of the PCV for a second time (at the front of JFK's head) for the HSP to exit from the PCV. The contained material is stationary except for wild oscillations, while being compressed ....even though the HSP is racing through it, and it is highly compressed as well as stationary. Given the release of an exit point breech in the PCV made by the exiting HSP, the stationary contained material begins to rapidly accelerate out of the created exit hole. The compressed contained material very selectively avoids using the HSP entry hole into the PCV as an exit. The subsequent accelerating flow of formerly contained material out the properly selected exit channel then creates thrust that turns out to be much greater than the original KE energy of HSP, demonstrated by how rapidly it moves the PCV in the opposite direction as the HSP is moving. The PCV (JFK's fractured head) that was completely resistant to moving forward now then will move backward like a tightly filled untied balloon that has just been turned loose.

There was a test and Con Man Rahn failed it !!!, as the lone gun man theory has far more holes in it than JFK's corpse.
FTR the apex of goofiness in your claims is centered
on created "propellant-like" "jet" thrust generated between the miraculous interaction of the incoming bullet and JFK's Pressure Containment Vessel head and brain matter based thrust medium that so effectively overwhelmed and counter acted the energy of the bullet as Kennedy's head was effectively moved in the opposite direction that the bullet was traveling.
but I have to give you credit for having a ready made butt load of logic pulling explanation-like material, as concocted by some one else to save you the trouble. I bet that speeds up your typing rate just like the "jet effect" that Rahn talked about.
Too bad that the magic bullet did not manage to collide with Rahn's head to create another example of some momentum reversing "jet effect" using Rahn's own head so Rahn could be an even bigger ex spurt (right out the exit hole in his head) on the topic.
Con man Rahn probably has some extensive calculations on how fart gas and the gravitational pull from the spin of Saturn also play into JFK's backwards head movement as JFK was killed from a shot from behind, among all his other basically meaningless because he can not really keep track of what is what number plays.
