Makes no sense

Makes a lot of sense to me. Tain't all that easy even with image
comparison. Too many variables, irregular shaped objects, and
changing landscape along with no recent data/images for a base line.

We can easily find lots of things when we are looking at either a
small area for something specific of any area where we look for
"anything", but not something specific in a very large area. That is
extremely difficult. When it comes to pattern recognition, computers
are very good at looking for some specific shape, but not good at
finding that shape when it's been altered. The algorithms for complex
pattern recognition are very sophisticated and typically take lots of
computing horsepower.

On top of that if there is any brush around, airplanes can be
extremely difficult to spot even from 500 or a 1000 feet.

A Bo went down between here and MOP a few years back. That area runs
probably between 50 and 100 people per square mile. They put it
between two trees and walked out. The FAA inspectors couldn't readily
find the plane so to save time the two guys took them back in and as I
understand it still took them a few hours to find it.
