The civil defense booklet "Your Protection Against Nuclear Attack" didn't actually exist. A civil defense booklet did exist at the time of the film's production, but was titled "Advising the Householder on Protection against Nuclear Attack."
The so-called Honest John 'missile' shown during the first half of the film is nothing of the sort. It is, in fact, nothing more than a NATO-type external aviation drop tank, and bears absolutely no resemblance whatsoever to an Honest John.
