Hah! The version I played didn't allow you to specify 180 degrees, although it did allow negative burns. So you could tweak your fuel supply by careful negative burning, but it required some balancing work to actually come to a safe landing. Of course, if you wanted to just quit out in a hurry, all you have to do is a straight-down burn of -9999999, and bam, you're on the ground, with a Captain Haddock style of "We shall end up by arriving, I suppose".
