The road to Create Aeronautics
youtube.com
Create Aeronautics, along with other mods from the "Create Simulated" family, are addons for Create that push the mod into the realm of physics. This video talks about the state of the mods, what to expect, and some teaser clips and pictures.
There was also a blog post by the creators themselves that contains some of the same information and teasers, if you prefer that format.
Can't wait for Create, i'll have to watch this later.
Also, oh hai Copygirl!
Looks cool, best of luck.
