It should be emphasized that there are many uncertainties in the assumptions underlying the description of the results of a 1-megaton surface burst in Detroit. Nevertheless, several features stand out:

	•	seventy square miles of property destruction (2 psi),

	•	a quarter million fatalities, plus a half million injured,

	•	additional damage from widespread fires,

	•	rescue and recovery operations must be organized and heavily 
		supported from outside the area (food, medical, utility restoration, 
		and cleanup).
