Agree about the authors especially Abraham Gubler who was a former poster here before my time and I wouldn't have been surprised was a Moderator or a DEFPRO at least. If Abraham wrote it then its pretty well spot on.Before we all jump on @Depot Dog, I'd point out that APA didn't write those articles. They are Defence Today articles. APA does host a number of good references they use as primary and secondary sources; in this respect the offer value to defence analysis.
While DD wouldn't know, they are also written by two respected names and nothing in them looks out of place. I will quibble with the cost and time figures in the turboprop conversion article; but as sources both are fine.
I haven't visited APA in years.
