Ebola Reston (which fortunately only affected non-human primates) did spread through the air, or at least that's the only plausible explanation as to how it spread.

While the outbreak strain of Ebola may not be airborne now, it's not inconceivable that it could mutate at some point.

"In the first known case of what may be transmission of the Ebola virus from a pig to a human, a pig handler in the Philippines has tested positive for a strain of the virus, world health officials and the Philippine government announced Friday."

"But the strain — Ebola Reston — is not known to be dangerous to humans, and the worker, who was infected at least six months ago, is healthy, officials said."

It should be noted that "airborne" and "highly contagious" are also not synomymous.

That's the plot of the movie Outbreak.

And the much (!!) better (and functionally non-fiction) book it was based on.
