Airdrop animation help

Im making airdrop similar to rust so if i throw my custom projectile or just once every 20 minutes on a custom block, i have the airdrop block but i dont know how to make it spawn a airplane from farthest loaded chunk of player and flyes to oposite when it is above the location it drops the block that will fall slowly and the plane should despawn at farthest loaded chunk any guess how ? (P.S sorry for my bad english but im not native speaker.)
