Oh come come now Irv, I think you're being a bit over-generous ascribing these techniques to as late a period as the 1960s!
In the first half of WW2 British scientific intelligence was telling the RAF that dead reckoning was no good as a method of accurate navigation. They didn't listen, despite the Butt Report revealing that most of their bombers got nowhere near their targets. They continued to resist the development and introduction of radio-based precision bombing aids (they didn't need them apparently) and generally thought that they knew best. Of course, they didn't.
It's an interesting parallel with the CAAs attitude to GPS half a century later, and the two organisations are not exactly unrelated. Old attitudes die hard, it seems.
Most Secret War by R V Jones is an excellent read.
