In a recently released computer game there is a scene where a nuclear bomb goes off in space over the active war zone on the east USA coast (too high for anything but EMP). Moments later, it starts raining helicopters and everything that uses electricity, from lights to laser sights goes out. Curiously, diesel generators appear to keep working, continuing to power the supposedly-burned out lights in one place. In another media thing, a TV series, when a nuke is about to go off all the computers are turned off "to prevent them from being damaged by EMP". How much sense is there in these scenes? Will some class of modern helicopters be brought down by EMP alone? Does being on/off matter for a laptop against EMP? What devices should be un/affected by it? And, second question - human brain and body is pretty much an electronic device of a distinct design, how is that it is completely unaffected by EMP (or is it?)?
