Aircraft are split to seperate repositories, under the FlightGear Aircraft project at Gitorious.
How to split an aircraft
You need to have up-to-date fgdata to do this. There are two workflows that both do the trick:
Method 1
cd fgdata git subtree split -P Aircraft/737-300 -b 737-300 cd ../split-aircraft/737-300 git init git fetch ../fgdata 737-300 git checkout -b master FETCH_HEAD git push git@gitorious.org:flightgear-aircraft/737-300.git master
Method 2
(need to check this one)
cd fgdata git clone --no-hardlinks /fgdata /737-300 git filter-branch --subdirectory-filter Aircraft/737-300 HEAD -- --all git reset --hard rm -rf .git/refs/original/ git reflog expire --expire=now --all git gc --aggressive --prune=now
