    Just to add an example, the recent DSP orbital insertion burn
    (or its exhaust plume) that a number of people saw from widely
    scattered locations was in part an inclination change.  (It was
    also of course to circularize the payload's orbit from GTO to 
    geostationary.)  Here's a link to one of the threads about it:

    I can't say much about the physics, but I do know that one 
    advantage of launching from the equator (Sea Launch) or near it 
    (Kourou, French Guiana) is that it costs less in terms of 
    inclination changes.
