- Do not overwrite the c key (toggle-cockpit). Use t instead.
- Do not overwrite Ctrl+A (altitide hold). Use Ctrl+Z instead.
- I found that the human models are very bad for frame rate. That's
OK as they are optional. What is not OK is that enabling them also
forces all remote players to render them (there's even a boolean
sent over MP for this). Therefore, I hereby disable the human
models on Citation IIs that are not the local aircraft. Maybe in
the future we can find a way for remote FlightGears to accept or
reject the rendering of these human models even if they do not fly
the Citation II.
