After flying to the customer's destination, the Zip will hover about 300 feet in the air before lowering to the ground. Zips automatically avoid obstacles and gently place the delivery at the guest's address.
This doesn't sound like it would work in areas with above ground power lines.
I'm talking about the tethered delivery system used by the drone to lower the package.
