As a fan of TNG, I am so happy this book exists so that not all of the books are about TOS. It really reminds you how HUGE the 1701-D was compared to the 1701, and illustrates its longer-term mission with thousands of people living on the ship for an extended period of time. In fact, you could say that Starfleet's greatest accomplishment was not scientific or tactical, but one of management. How else could you get a crew of hundreds or thousands together on a ship for months or years, not always in contact with HQ, and have them all performing near 100%, and not have a disaster? The part about how the ship was built was fascinating. It took 20 years from the Galaxy Class Project's approval in 2343, to the extensive testing starting in 2357 once hull integrity was complete, to the Enterprise's official commission at Utopia Planitia Fleet Yard on October 4 2363. I also liked the descriptions of how the transporter and phasers work, though the replicators could use some more detail. It can be hard to tell how much of it is real and how much is fantasy. It is a joy to read this; it reads like a textbook except there is proper spelling and grammar, a simpler sentence structure, and the subject matter is actually interesting. The pictures and diagrams are in black and white but they are so clear you won't mind.
