All that I’ve been hearing from SurvivalBlog readers thusfar about the National Geographic documentary Electronic Armageddon has been positive. It is about the effects of a High Altitude Electromagnetic Pulse (HEMP) on the US. Check your local listings for repeat showings! For further research on this topic, I highly recommend the EMPact America web pages.
