"The year is 1975. Deep underground in a Top-Secret Nevada laboratory, funded by the United State's of America's government, the SS-15 Self-Cooling Superjet was developed. It was designed to break the pull of Earth's gravity, without the use of Rockets. The Mark I couldn't even lift off the ground, but the Mark II proved itself, being able to carry a 50,000 pound load into space - and back. For the next 250 years, Multiple Superjets were used for intergalactic travel, some more advanced than others. They are extremely loud, power-eating, slow engines, but these led up to the engines that the modern-day Ares and BAN use. Some other drawbacks are that you had to have a man INSIDE the jet, to control it's functions, and you had to cooperate with all the other jets to get somewhere! That's your engine history for today class, remember to study and write a 150 word essay summarizing the Superjet, and bring it in tomorrow!" The teacher said.
So here is a quick build I made, and I am going to start using these, and any of you can to, for some "older" starships. Well, atleast the concept of it. Take note that I'm not as good as Comr4de or Tingalz at building things like this, so it may be a little ugly. I kind of like it, though.
