<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">up above</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for aloft that I've seen before include "Up in the sky" , "In the rigging, up high" , "as 1 ac [PEGASUS] was?" , "Up in the air, high above" , "up the mast" .)
