When Native Americans were in the majority in Los Angeles, they called the
basin the "Valley of Smokes". The smoke from anything burned tended to
rise a bit and then join fogs and haze to form a layer of murk.
A few years ago a 747 approached Hawthorne airport for a landing,
thinking it was LAX, and pulled up at the last minute. The (1) runway
at Hawthorne is much shorter than what a 747 needs, but more or less in
the path of an eastern approach to LAX.

when I see the lights of L.A., even from a plane, I am well
within the dome of influence of pollutants, as it's during either
an approach or a departure. But I think the idea here is that the
color characteristics- spectrum, amplitude, etc. are more noticeable
when the source is somewhat of a point, rather than when it is providing
