On the level delta halo, take the scorpion from the bridge onwards,then take it through the tunnels into the clearing with covenant shields in a cluster.Kill the enemies, then fire at the shileds until they all disappear. when they do quickly position the scorpion over the shields. when they regenerate, they will pass through you.now you are like this just try steering, and you will go flying really far!!!If you try it again and again, you may ever spin in midair!
