DLR contributes, but different others fork
NASA Ames:
Early contributor
Fork later
Problem of code property
Solved through opening the code

Open Source in Aeronautics and Space Research
Conclusion
We make our software more and more available as open source
Enables contribution
Supports cooperation
We use more and more open source
Profiting by stability of open source code
Writing less code
