I said that somewhat tongue-in-cheek, but the line between "drone" and "missile" seems to have gotten pretty blurry with the Ukraine war featuring FPV drones holding a hand grenade that are effectively a human-piloted missile.
Some modern missiles can fly around to identify targets, but they can't return home. They can blow up harmlessly if nothing is a target, though. They can also dodge and weave the way FPV pilots do.
Obviously, "drone" has a much more expansive mission profile than "missile."
Missle is a projectile, propelled by rocket motor. Drone is an aircraft vehicle, capable of transporting explosives or whatever. There is a fat line between drone and a missile, there are different in everything: control, speed, trajectory, weight, flying principles. I don't know how you can say they are even close. Just because both fly and do boom? Then you can say there is a thin line between cow launched from catapult and a missile.
