Gee, I hope Scotty's OK. I wonder where???
Kidding aside, I worked at a dive resort where the senior staff would reminisce about the time the black choppers landed on the beach and the resort manager was removed by the boys in black.
(He was later released in another country with no money and incomplete documents and left to make his own way back home.)
I eventually met the man and got the story first hand.

The sound was unmistakeable on the raised floor, akin to the 400hz whine you hear in the heavies (aircraft) kind of cool
Also kind of cool doing a cold power start on one of these puppies.. A stepper switch in the main processor unit bought up one peripherial system unit at a time to spread out the power load ramp up. Each unit was remote started via control lines in the EPO cable (power start/power good handshake that advanced the stepper switch).

It is not only military weapons and aircraft that use 400Hz power systems. Commercial aircraft use them as well. At each Passenger boarding bridge we have a connection from either a centralized 400Hz distribution systems or in the case of newer installations, a point of use MG set mounted right to the bridge to power the aircraft when the engines are not running.
We had a few fail last year and the airports we are involved with seem to be moving toward the point-of-use systems.
Just FYI
