I think the answer to that is "yes", since our technology is advancing all the time. The question this made me wonder about is, "If this new 2015 engine was given to the 1970s engineers, would they be able to understand how it was made and create a similar one?" This is just 40 or so years later. It makes you wonder how advanced an alien civilization would really have to be to impress us.
