Re: NATO task force can't read Morse code?
That would be suprisingly easy to do, as I studied how to use a webcam to mock as a Quality Control in a plastic bottle production line.
Camera sees bottle with cap, pass.
Camera sees no cap or no bottle at all, fail.
You'd need to add some form of timer, an output translator, and boom, even a CRT monitor safely tucked away at the bridge can be used as a source with a webcam looking at it.
You can even do it on the infrared range, at your leisure.
