I have a question for the designers and builders of Starfleet ships. Why do you think we have seen very little alien influence in ship design in Starfleet. I'm talking more TNG and beyond. By TNG time other Alien races must have entrenched themselves in all aspects of Starfleet operations. So you would think that would included Starship design. I guess there could be "under the hood" kind of stuff, but the overall ascetic of Starfleet is human design.
