[zaidmo]

I was wondering if the word "open source" is being used correctly in the context of aeroplane parts.

Dictionary.com has 2 definitions:

1. Computers. pertaining to or denoting software whose source code is available free of charge to the public to use, copy, modify, sublicense, or distribute.

2. pertaining to or denoting a product or system whose origins, formula, design, etc., are freely accessible to the public.

I guess the latter definition could apply, where the components can be produced (e.g. 3D printed) from detailed "open source" blueprints? However, I dont think the plane will be built from 100% "open source" rendered components. Generic or branded components may need to be purchased as well.
