Does anyone know if the Amazon delivery drones follow a flight path? I've always enjoyed watching the different planes that I can see from my backyard. I could possibly live near or under an approach path for a local airport.

Amazon is expanding their drone delivery market to my area... I saw a few of their delivery drones flying around recently. It was a jarring experience to see a large drone zipping by while I was walking my dog.

My question is, do the Amazon drones have an approved flight path that they follow? If not, should I prepare for these things to be buzzing across the sky while I'm my backyard?
