My understanding from Ammerman is that the western edge of V-23 is at Woodland and the I-5. From there it extends 9.2 statute miles eastwards. Battleground is approximately 8 miles east of the I-5. So everything kinda fits.
In addition, Heisson and Amboy are in the 12-14-mile-east range of Woodland.
Follow your own reporting/interviews. Focus on that! It's worth noting that the AF had a tactical (Defense Mission) interest in knowing where 305 was. This is all happening on 11/24 in real time. This was a real time defense mission with lawful options open and available. This was NOT some bunch of Cooper aficionados speculating about some hijacking going on with who-what-where and would there be a Cooper Con this year? I am relatively certain Scott/Rataczak/Anderson were aware of the military tactical options now on the table should their hijacked plane come to pose an actual risk to the public or National Defense, based on events unfolding. The F-106's had an actual tactical mission. This was no game.
As a result a review of the matter was conducted - routine: "The flight path coordinates were calculated from data tape recorded at the McChord Air Defense Command Direction Center (DC). The calculation and the plotting were almost certainly done by the McChord detachment of the 84th Radar Evaluation Squadron (RADES). It was their job to do such analyses, and the DC were just users of the system. It was all in a day's work for them.
The flightpath was produced by experts. Within the limits of its precision, it is right. Unfortunately, the precision is only one minute of latitude and longitude. And, the times associated with the plotted points may be off by a minute. AND,
it appears we don't know accurately WHEN Coop jumped due to the pilot not calling it in, except that the NWA and USAF people who did the '72 search zone map thought (with benefit of the "pressure bump" signature on the flight data recorder) that he jumped at about 19 seconds before 8:11.
That could off off by a minute or two and everyone realized that."
Very like the FAA was given a report.
