It's happening, precision GPS is coming to the airline biz,
bye-bye omnis, FAA jobs, whatever.

My daughter and her husband farm about 2,200 acres of corn and beans in western
Minnesota. Their combines, fertilizer spreaders, planters, etc., are all GPS
equipped. As the crop is harvested the combine keeps a yield-vs-GPS-location as
it passes across the field. Next spring that data is networked to the
fertilizer and planting rigs who compare it to last years settings and their
rates are adjusted on-the-fly to optimize the yield down to a 2-meter
resolution. Interesting that some idiots here had the loopy idea to turn that
system off once in awhile just for grins --- military weapons system and all
that, doncha know!
