Quiz Guy John Chaneski has lifted some tricky puns from New York Times crossword puzzles for this word game. What's "a green org," in three letters? How about a three-letter answer for "peas keeper"? This is part of a complete episode.
Was listening to an interview with Will Shortsz, the bane of many a crossword puzzle solver and he said one of his favourite clues is:
A great tower (3 letters)
I'll let you know when someone answers correctly or next week so as not to spoil the fun.
The C47 is a military transport plane used for towing other aircraft. There are other air transporters of even shorter names, though some of which may not be considered 'tower.'
Good try but you don't usually get numbers in crossword puzzle answers, but you're on the right line of thought.
So as not to give it away all at once in case I've got it: just because the clue specifies 3 letters doesn't necessarily mean they're three different letters, right?
