> But then how do you deliver to the upper floors of vertical buildings?
Elevators, dumbwaiters, baskets and pulleys, or just go downstairs and get it yourself.
Also, how tall are we talking? Where have you been where the upper floor windows actually open?
edit: the more that I think about this, the more it bothers me. Getting close enough to a building to deliver a package through a window with a drone sounds incredibly improbable and dangerous. A small gust of wind and the drone crashes into the building. You'd need some kind of pad at a distance from the building, or use the roof. Looks like there's a design for that[1].
And what if a package or drone falls from such a height?
I think the concept on its face is flawed, but then again, this exists[2].
