Driving a car vs. flying an airplane- which is more difficult?
car: 2 dimensions (x & y axes); plane: 3 dimensions (x, y, and z axes)
car: usually less than 70 mph; plane: 600+ mph
car: follow the paved road, avoid other vehicles; plane: follow the flight plan, avoid mountains and tall buildings, avoid bad weather, avoid other flying objects
We already have planes in production and every day use that can fly and even land themselves.
