I noticed a scheduled Gypsy moth pesticide spraying mission in the local news. The areas to be sprayed are fairly large in an a generally populated area. I notice the spraying plane will run this mission at 250 feet of altitude at a speed of about 160 mph.. I'm curious as to what notification / warning will have to be issued to UAV hobby pilots. This is all developing and it just underscores how complicated it may become to share the airspace above us.
