It is a necessary evil, to some extent. The aircraft in FGAddon as well as FGMEMBERS must be released under the GNU General Public License license.
The GNU GPL is a license that will help aircraft live longer, by letting users copy, use, modify and redistribute aircraft (provided they are published openly; GPL is free as in 'free speech', not free as in 'free beer'). In essence they can be maintained even if the original author would have abandoned them.
Something I would wish aircraft developers starting a new aircraft would do is have the phrase or (at your option) any later version in the preamble. (See the 'How to Apply These Terms to Your New Programs' section after the license text of GNU General Public License, version 2. As it is now only some very few aircraft could be moved over to GPLv3 should the need arise.
@IAHM-COL: Relax a bit.

IAHM-COL wrote in Mon Mar 30, 2015 6:36 pm:So I get that it is GPL.
I will mount it in FGMEMBERs so our FGDATA next users can fetch, and enjoy.
I Will leave a note there that you are not currently willing to receive issues and reports, so they won't be bothering you.

IAHM-COL wrote in Sat May 09, 2015 3:57 pm:It is my understanding that airplane models looking for inclusion in FGFS need to be covered under GPL type of licenses, and thus I am afraid you may need to compromise with this one (as opposed with MIT license)

Think about it this way: you can include public domain content into a GPL'ed project, but you cannot include GPL'ed content into a public domain project, due to the viral nature of the GPL and its requirements, which would render all of the work "GPL" otherwise.

You mentioned your intent on your participation on the Shuttle was not GPL but Creative Commons.
Yet you began modifying and working on a GPL project with Thorsten.
Could you please verify that the SpaceShuttle remains a fully GPL compliant aircraft, in spite of your participation?

No, he didn't - read the thread.Could you please verify that the SpaceShuttle remains a fully GPL compliant aircraft, in spite of your participation?
He can't (and you know it) because he has no commit rights on the repository. So sorry, you'll have to deal with me for the time being. The statement stands that what goes to FGAddon is GPL material - live with it.
IAHM-COL wrote in Wed May 20, 2015 8:29 pm:I am unaware of the exact meaning of your statements above. In particular in what is related to the legal issues of the situation you are proposing. In particular I am having trouble to keep recognizing that 1) you have good intents related to the GPL license of the shuttle, and 2) that you want to be an open participant in the development of GNU covered software =such as Flightgear and the Shuttle.
Let me first remind you of the declaration of intent for Flightgear, as seen in the Readme file of FGDATA
http://sourceforge.net/p/fgdata/submodules/ci/next/tree/READMEThis project is GPL'd. For complete details on our licensing please see the "COPYING" file.
An important provision of GPL (among the most important ones) is "Copyleft".
It is not a very complex concept really. But it is centerfold to the enpowering of user's freedom provided under the GPL letter.
