You're basically saying something analogous to taking a creationist vs. evolutionist, or
old school approach to the problem. Vallée, like Keel, has injected new ways of seeing; because, the nuts and bolts paradigm is not enough to explain what is taking place.
We're not just passive observors in this conndrum. There is also an interaction between us and the UFO/UAP that suggests intentionality, that we may on occasion experience internally, that appears to be connected to our history at specific points in time, that shifts in its appearance, is even something we appear to be co-creators in at times. Let's face it; it's a highly complex, dynamic phenomenon that we have been interacting with in a limited and inexplicable manner for quite some time. In short, it is an evolving phenomenon that appreciates new paradigms to study it. That old nut and bolt theory is rusty.
MacDonald and Hill have explored the physical sciences at work and they're just speculating based on the limited, weird evidence that is available. Vallée is pointing out new directions, new contexts, and is doing what a good scientist should do, which is research fresh, undisturbed evidence as often as possible, collect and notate as much evidence as possible and seek out patterns where possible, He's at least got new theories - you got game?
Duensing suggested that he has written the software to do that mass, big data tabulation & analysis as funded by Bigelow to see what unrestricted and unbiased, tabulations will yield. That sounds like a good use of resources as opposed to leaving your organization's decades old collection of UFO files with some crooks, or peddling your abduction tapes. Integrity is difficult to assess and come by in this field. Vallée is one of the few legits that has climbed some different hilla and has shook the tree of ufology good and hard to see what shakes loose.
What do you think we should be doing with the data, and who is going to find it & fund it?
