The thing is that rather than grabbing serious drawings or plans, they grabbed abbreviated ones that were obviously used for training and the type of doodles someone qualifying on a system would make to explain their knowledge (military personnel proving they know enough to trust/fly/maintain their gear). And got utterly obsessed with a hex transformer (uses multiple transformers to shift the waveform of ac, then converts the peaks to get really high voltage DC), declaring alien technology that would never work. It really drove home the point to me how easy it is to eventually find a professional that will say what you want.
