Hello All.

It appears that Mark has just volunteered to be this site's Geographic Information System technician. In a GIS environment this entire data set could be queried by any field or combination of fields as in: List all owners located in the State of Florida having an aircraft of model year 1975 and newer or click on any state or zip code polygon to list all registrations within or better yet make the data interactive as well such that mousing over a registration point would display the entire data subset. Solicit pictures from the owners and hot link them to the registration data. Mine TAP, Controller, etc. for aircraft for sale allowing the query "list all aircraft for sale within 500 miles of Memphis". The possibilities are almost endless. I'll await further development, nice job so far.
