How is that any different from an automobile navigating the ridiculously crowded streets?
Presumably, if you're going to bother with flying vehicles, it's to free up space on the ground below.
To fill with other uses, say pedestrians.
Taxi falls, pedestrians get crushed bellow, but now the vehicular speed isn't 20-30 mph tops, but the terminal velocity of the vehicle.
mv^2 is mean.
Much worse, obviously.
