Am I doing Cframe correctly?

This is a script for an AI drone. The drone is supposed to slowly glide to the position of the player. However, nothing happens. There is no errors in the output.

local Vehicle = game.Workspace.AIVehicles.AIPlane 
range = 200 -- the range that it attacks you from
while true do
        wait(.1)
    plrs = game.Players:GetChildren()
    for i,plr in ipairs(plrs) do
        if plr.Character ~= nil then
            head = plr.Character.Head     
            if (Vehicle.Position - head.Position).magnitude <= range then
local GoTo = head.Position
local Speed = 2  --How many studs to move at a time.
local Debounce = false
local Direction = CFrame.new(Vehicle.Position, GoTo).lookVector
function MovePlane()
	if Debounce then return end 
	Debounce = true
	Vehicle.CFrame = Vehicle.Cframe + (Direction * Speed)
	wait (0.2)
end
Debounce = false

            end
        end
    end
end
