Check out DCT Bennett
Howabout et al,
You should do that, it will illustrate exactly what Sunny is talking about.
Read the book, Star Dust Falling, by Jay Rayner, where the intransigence of AVM Don Bennett, and the way he ran British South American Airways, where he was completely resistant to change (particularly changes such as the use of DF, much less ADF --- none of that Yankee horses----t) created disaster.
DR and Astro for navigation, nothing more.
Or read the accident reports on the losses of the BSAA aircraft, the Government inquiries, and the company finally going out of business, having first established a second to none history of losses of life that made it, by far, the most dangerous of the post-WWII British airlines.
Back in the day, (I still have mine) we all had to have a copy of "The Complete Air Navigator", the textbook for aviation astro-nav, but???
There is no question of Don Bennett's critical contribution in WWII, aka Pathfinder Bennett, and equally, there is no doubt about his disastrous contribution to civil aviation.
There is no equating those who serve in the military in wartime (or any time), and then move into successful aviation careers in the civil aviation field, and the type who moved directly from military retirement straight in a government civil administrative job, with little (generally nil) civil experience, and all too often a mindset that was variously skeptical, suspicious or downright anti "profit orientated commerce".
The general attitude that "commercial aviation" has to be rules with a rod of iron, because "civvies" will automatically cut corners at every chance, to minimise cost, and completely ignore the safety of the passengers is hardly unknown.
In short, the "military mind" that Sunny is talking about is completely distrustful of civil aviation, the civil approach to administration, and all those employed therein.
Of course this doesn't apply to the majority of military/ex-military persons, but it does apply to enough that it has been a long running disaster for civil aviation in Australia, right back to civil aviation administration in Australia commencing as a branch office of the Air Ministry, under the redoubtable command (yes, command) of one Lt.Colonel H.C.Brindsmead, OBE, MC, first "Controller of Civil Aviation".
