First fresnel zone is 57 feed in diameter at 15 miles.  How long is the path?
You need a 60% blockage or more of the first fresnel zone to really kill you.  

So would a blade be that wide?  Would a blade be directly in the fresnel zone 
both in altitude and azimuth?

Looking at linkplanner kmz in updated google earth on a problematic link we 
have there are now 3 windmills in the path (300 foot windmills if i recall 
correctly) but theyre at 11,13, and 15 miles out. The 11 is centerline and the 
other two are maybe 50-100 feet off the centerline, per google maps 

I cant see that at those distances there would be much impact but wanted to 
make sure all my goats are pleasured before i move on.
