Hello Steve,

For the geographically challenged: Hurricane Sandy came ashore in
New Jersey. About ELEVEN HUNDRED miles from Cape Canaveral. Which,
give a few hundred miles, is the closest distance from Florida to the
Pacific.

Sandy began as a Tropical Wave in the Caribbean on October 9th.
Tropical Storm Sandy then hit Jamaica'mon on October 24th and was
upgraded to a hurricane at that point.

There were, within a very tight constraint, the same number of hurricanes in the period around
1855-1874 as their were from 1975-1994

And that was in a period before modern reporting versus advanced
climatology. There were more in the 1930's to 1950's
(pre-space-race) than there were post-lunar-landing.

 Here's the major hurricanes since 1851:

 If you think you see a pattern of "they're hitting around where
 launches happen" (assuming they did in the 1800's, a pretty poor
 assumption) - launches happen at the equator, or as close to it as a
 country can get, because the rotation of the earth offers-up
 additional free escape energy. The diameter of the earth is about
 8000mi * PI ~= 25,000 miles. The surface of the earth at the
 equator is moving around 1040mph, where even just 28.5 degrees
 north, at Kennedy, it's only moving at 900mph. The fuel required to
 overcome even that 140mph when we're talking about several million
 pounds is tremendous. The free boost is a financial and technical
 key!

 Hurricanes are born near the equator because that's the area of
 warmest waters and favorable winds. There's actually a very small
 sweet-spot for their birth along each major coast.
