I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">the jets for one</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for gang that I've seen before include "Informal body of friends" , "Criminal mob" , "Organized group of workmen" , "Group; clique" , "Criminal bunch" .)
