Why doesn't the bodyposition make the plane fly?

so I have this big Plane and inside of it is the BodyPosition and with this script ~~~~~~~~~~~~~~~~~ wait(1) local part = script.Parent local target = game.Workspace.Finish part.BodyPosition.position = target.Position, target ~~~~~~~~~~~~~~~~~ but when the script fires the plane still just falls outta the sky and doesn't move heres the Properties of the BodyObject

so if someone could please PLEASE help me out i've looked all of scriptinghelpers.org the actual roblox forums and tried looking at free modeled planes to see if theres anything

this plane is for a scripted event not to fly please don't give me something for players to use (it is triggered by a tool)
