**********  An interesting proposition... Aircraft windows are wide enough
to get a single camera 3D view by moving the camera sidewards within the
window frame between shots. This gives 3D to the wing and engine, while the
aircraft's movement provides a stereo distant view. If you have a Realist or
other fixed stereo camera, take two shots. You'll be able to cross-mix the
pairs for two stereo scenes. Remember to move the Realist sidewards between
the two shots as if it were a single lens camera.

**********  This should be easy to figure out if you can remember which eye
is which. Looking out the left side of the plane, the FIRST shot would
correspond to your left eye. Looking out the right side, it would correspond
to your right eye. With a twin rigged camera you could reverse the order and
end up with a normal stereo foreground and a pseudo-stereo background! That
might be interesting.
