This is another Star Trek-like starship, the LX-01 Explorer. As you can see, it really looks like the ship of the Enterprise TV show. I build it from the Bonaventure starship, another lego® creation (the Bonaventure was dismantled to build the Explorer). The saucer is larger, I added twin hulls, but the wings and the nacels are those of the Bonaventure. The Astronauts enjoy a taller ship :o)
There is only one access, between the hulls at the aft of the saucer.
