Donna leaves the house
As Donna left the house in the morning for work, John wished her a nice day and then ran upstairs to go and get his drone before she drove out of the driveway. He prepared it just in time and launched it from their backyard and Donna drove off for work.
The drone flew high above her, so high that you could not see or hear it, even if you tried to find it, it would be almost invisible to the naked eye. John piloted the drone from his house and watched on the screen what was going on down below.
