This facility would do nicely for anyone who wanted to animate ejection seats. I think an underslung load ought to "sense" the ground, so I'm now tinkering with adding some simplistic ground reactions to ballistic objects, but I'm trying to avoid constructing another FDM. I hope that I have guessed Maik's requirements correctly.
