Just finished a book where America gets whacked by a sub orbital Nuke. Thus wiping out anything electronic, including the bits on the Presidents plane. (Bye, bye Mr President.) The questions are; Are modern vehicles E.M.P proof? (probably not) How old would the vehicle have to be to withstand an E.M.P blast? 50s, 60s, 70s, 80s? How E.M.P proof are, the old Series IIIs? What other types of vehicle would be E.M.P proof, Ford Sierra/Cortina/, LR Defender? Is there anything from the last decade that would stand up to an E.M.P blast? Yours with extreme paranoia, SK p.s The book was called " One second after " by William R. Forstchen. Think it was recommended by another ARRSE member.
