I can see that the flight path discussion is a very controversial one. That makes perfect sense.
To be clear, I did not come up with the idea of a western path. That said, to the best of my knowledge there have only been three of us who have strongly advocated such a path--which by definition means the FBI flight path (Air Force) is wrong.
1] Tosaw factored in Tena Bar and considered that nothing had been found along the FBI flight path to arrive at a western path.
2] R99 factored in Tena Bar, the correlation between Maylay and Canby, the not-likely circuitous FBI path near Portland, the flow of the Columbia River near Tena Bar, and the placard to some degree to arrive at a western path.
3] I put a lot of weight on both Tena Bar and the placard find, and also considered the 8:12 jump time, the role of the Columbia River in all of this, the fact that nothing has been found along the FBI flight path, the "doesn't make sense" circuitous FBI path near Portland, and the fact that the FBI had erred previously via the Palmer Report, to arrive at what I call the 8:12 Arc Theory which points to a western flight path.
All of this said, Tosaw and R99 both believe DBC no-pulled. I believe Tosaw said he ended up in the river, and R99 believes he ended up on Caterpillar Island. I, on the other hand, believe DBC survived and landed in the Ridgefield National Wildlife Refuge.
I do not consider Tosaw, R99 or myself crackpots or drawn to conspiracies. I think the methodology that each of us has applied to arrive at a western path makes sense.
On the other hand, from what I can tell Shutter is the strongest--at least most vocal--advocate for the FBI path. This of course is based upon the Air Force's capabilities and the testimony of R2 in Seattle. That makes sense, is compelling and by default should be the accepted flight path.
However, Tosaw, R99 and I have, for reasons explained above, concluded that the default (Air Force) path must be wrong.
