I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">touch down</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 land that I've seen before include "Country, state" , "Secure" , "Ground; country" , "soil" , "Take catch" .)
