Interesting statement about the scientific “level” of the said NASA DC-8 ash encounter “paper”. While this paper originally is part of thousands of “studies” and “reports” on the NASA Technical Report Server (NTRS), it can now be found nearly “everywhere” for known reasons.
It seems, that your knowledge level and insight what scientific research work and analysis is really about is quite dim. While a pilot’s license puts you in the front seat of a complex and remarkable man-made machine, it unfortunately lacks the intellectual capabilities and skills of a profound Ph.D degree and experience in either engineering or natural sciences. The retroactive blaming of all aviation authorities, VAACs and its associated scientific advisors and risk management teams in order to follow the media mainstream is therefore a direct result of this lack of core knowledge.
Better work on the quality rather than quantity of your “publications”…
