Most wires generate a significant magnetic field with a specific geometry that can easily be uniquely identified from clutter, and be displayed in the NVGs. It worked decently, but at the time the sensor/google combination proved too expensive and not reliably enough to be commercially viable.

Fast forward to modern times, where cost and size reduction of EMF sensors could readily be remotely mounted and alerts presented via whichever flavor of GPS display in the cockpit, much like terrain alert tied into radar altimeter and/or database and displayed on the cockpit display. Would love to see some manufacturer resume that effort, as cutting down on strikes would drastically reduce the yearly fatality rate.
