One thing I've noticed (from the magic carpet mode) is that if you
call geo_direct_wgs_84() with zero distance and zero direction
(i.e. zero velocity) you don't get *exactly* the starting lat/lon back
because of numerical precision issues. This is not a big deal at

Well, the balloon lacks one significant thing for an FDM: enable the
plane to move around. The balloon model works nicely

The drifting is moddeled correctly and returnes me a displacement in

I was using the c172-yasim, and

Wow? What is programming about?
It should not be a question as to whether it is ok to
delete a null! Any allocator/deallocator of memory
can or may not have

Have you tried my Windows binary
http://www.vso.cape.com/~nhv/files/fgfs/fgfs.exe.gz
Initially JSBSim went crazy during the cfg xml read
( JSBSim Flight Dynamics Model v0.9.1 [cfg v1.57])
but this is caused by the cvs update adding things
like the following to %FG_ROOT%\Aircraft\c172\c172.xml
