Who the fork cares?
For whatever reason You are Ignoring the Loading of product ONTO a truck. You are also Ignoring the possible Staging of product when a Forklift Unloaded it Off of a truck, and that same product then being relocated throughout the TSBD via Hand Jack(s). And then there is your Ignoring the possible Fork Lift loading of product onto the rail cars situated on the Railroad Spur behind the TSBD. Maybe the Trump Exoneration has you on the wrong side of the bed today?
What "Trump Exoneration"? An acquittal by 53% of the US Senate voting "not guilty", is not an exoneration!In any event, have you ever heard of a dolly? It is armstrong powered, with 2 wheels, and a platform on the bottom for stacking freight.
This seems as good as place as any to post my two and half pages of notes (scribbles) of the first 15 minutes of the 41 minute oral history of Ken DuVall. I can still read most of my notes. Wherever Mr. DuVall speaks of his actions he uses 'we', as his co-worker apparently went where DuVall went. In this first 15 minutes Stephan Fagin (interviewer) tried twice to return to his observations of Oswald in the 2nd floor lunchroom In my opinion Mr. DuVall was somewhat vague and dismissive with that questioning. Please excuse the many spelling errors throughout the notes.
My concern would be with the Truck(s): (1) Where the Truck(s) were Specifically located, and (2) Were the Truck(s) still there when the JFK Limo passed by the TSBD? Based on the notes above, It appears the truck(s) were there During the time period the JFK Limo passed by the TSBD. If a Truck is Large enough to run a fork lift into and out of it, it is Large in general. This would mean the roof of the Truck/Trailer would be High Above the ground. Depending on the location of the Truck, this High Ground position on the roof of the Truck/Trailer would be a Prime Sniper Location.
You obviously have Never attempted to move a Loaded Pallet into or out of a truck with a Hand Jack or a "Dolly". Your "2 wheeled dolly" suggestion is Laughable.
