From Encyclopaedia Britannica  Volume 12 of Macropaedia, p 119, 1984
(From the entry on microclimates)

 The superior image is convex upward and results from temperature
 inversions. These are most prevalent at sea with warm air overrunning
 colder water. Under special conditions the ray may be trapped in a
 relatively shallow layer. Where this occurs, or when the curvature of
 the ray is close enough to that of the earth, very distant objects are
 seen well beyond the horizon and may appear deceptively close.

Unfortunately, the encyclopaedia does not say how far 'very distant'
is. I think, however, that it is reasonable to assume that 90 miles is
well within that range.


PS. Warm air overrunning colder water is almost certainly the
situation in the Florida Keys.

These are the official opinions			Mike Friedman
of my organization. So, TOUGH!!
