I always thought that the ability of the Intrepid class starship to land and take off was pretty cool, but my question is, why would you design a starship to land? I fully understand that the ability of a starship (or a part of it at least) to make planet-fall in an emergency makes sense, and Voyager showed that you could land if a planet’s atmosphere was to full of technobabble to beam through, but why else would you do it? I am trying to think of in-universe reasons why you would go to so much trouble to design that feature and take up valuable space with landing gear.
