"The rockets roar sent shivers (down my back?)" can be punctuated in two ways, depending upon whether it is more than one rocket. Singular : "THe rocket's roar sent shivers..." Plural : "The rockets' roar sent shivers..." Like many "fill in the punctuation" questions, there is no way to tell if the S is to make the subject plural or to form a possessive. If there were no S, you would add "apostrophe S" to rocket. If the plural form were irregular (e.g. "The potatoes skin had been removed"), then it would be obvious that the subject is plural and an apostrophe only is added. (some style sheets require the S even where redundant)
