Finally took out the P3 Professional today after almost three weeks of snow and freezing weather. I went to a place I frequent a lot because it's on the beach and this time of year it's quiet with not a lot of people. I made sure in the past it wasn't within five miles of an airport. It's close but still not in the "zone." Today as I go to take off I see there are major airlines flying almost overhead. They're close enough that I can see the names of the airlines very easy. Obviously I'm not going to fly when there's airplanes with hundreds aboard at a height that I can easily reach. I took out my iPhone and opened the Hover app and suddenly the Fly Zone has changed. I've never seen a plane anywhere near there. Do airlines change their fly zones at different times of the year? Not sure what to make of it.
