just to clear this up: The 787 in FGADDON is under which license?
How should I know? I wasn't ever talking about a 787. If there's a genuine doubt of its GPL or compatible nature, last time a license issue was brought up for a sound file in the forum, it was removed a few hours later and thoroughly investigated. So if you think it's wrongly licensed, I'd suggest you post your evidence to the mailing list where it belongs.
