I still like to ask the question of why something should be made, beyond the 'its cool' argument. I've seen a lot of people design stuff for very, very specific circumstances that they are unlikely ever to meet, and its a bit iffy. I doubt anyone would build a ship specifically for flying through custard, when the chances of it happening are, to be fair, pretty slim. How often is a starship going to need to sit at the bottom of deep ocean trenches, for example? I dont see it. Everyone else uses probes designed for the task, because it makes sense.
