The Star Trek Federation ship design is one of the most innovative ship designs in Sci-fi
Granted, I don't know all Sci-fi ship designs, but as a young kid growing up in Pakistan, the TNG ship design was awe inspiring for me.
I had never in my life seen or even imagined a ship like this. A saucer and nacelles. That's bananas.
I was so intrigued by it. I imagined for hours where the bridge was. Where the engine room and transporter room and living quarters were.
I was wrong in many cases, but those memories are some of best growing up. Such a unique design.
