You'll need to look up all the flight plans and tower data over your area to see if the "x" patterns are nothing more than the result of airplanes going to different places or in wide holding patterns. I'll bet that's what you'll find if you check it out. You could also log photographs by time and day over a period of a month or so to see if the x patterns are regularly repeated, indicating a flight schedule. Ken

Sometimes it is two planes that paint the X and sometimes it is one plane that turns around to paint the other half. Then they wait a few minutes, and then start painting the grid pattern. In almost all cases the grid pattern is painted on the upwind side of the city, that is if the X moves south, the grid will be painted offset to the north. > >As far as hitting a field with pesticides you are looking at a few acreas, maybe 1/10 mile in length. A city is 5 to 20 or more miles in diameter, so it would take a lot more drift to make you miss the target. Of course the trails are higher than when spraying a field, so they still need to try and judge the wind and compensate. That is why I believe they almost always paint an X over the city first. > >Marshall > > >-- >The silver-list is a moderated forum for discussion of colloidal silver. > >To join or quit silver-list or silver-digest send an e-mail message to: >[email protected] -or- [email protected] >with the word subscribe or unsubscribe in the SUBJECT line. > >To post, address your message to: [email protected] >Silver-list archive: http://escribe.com/health/thesilverlist/index.html >List maintainer: Mike Devour <[email protected]> > >
