Rocket launch site (3)
I believe the answer is:
pad
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">rocket launch site</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for pad that I've seen before include "protection for member" , "Stuff the animal's foot" , "Helicopter landing area" , "Block of paper; go silently" , "pack" .)
