For the record, just because it hasn't been mentioned yet:
1) Mylar bags, the type used for food storage, WILL NOT protect electronics from an EMP. The reason is two fold, first is the way the aluminum film is applied, and the second is the way the bags are made into a bag. You need a minimum of 45db of shielding to protect electronics from an Nuclear EMP blast. A standard Mylar food bag will only provide about 10db of attenuation because the edges are not conductively bonded together. Mylar food storage bags were not designed with electrical properties in mind.
2) The cheap static bags that come with consumer electronics will only provide about 20db of attenuation, maybe 30 for the better ones like what computer motherboards come in. If you want a real EMP bag, you should be one designed for the purpose of protecting extremely expensive electronics. Check out the Dri-Shield 3400 series. A single layer bag (10 inches x 16 inches) costs about 80 cents and will provide 45db of signal attenuation between 1 and 10 GHZ.
The Dri-Shield 3400 bags will do the job for 90% of electronics, 90% of the time. If you want absolute protection, use two of them, on inside the other, with a plastic bag between them.
If Morgan's NV googles came inside a manufacturers static bag, and that bag was inside a metal vehicle, and they were turned off, it might have been enough for them to survive. I certainly wouldn't bet on it, but I wouldn't say its unlikely either. Its definitely possible they could have survived.
