Solid Patch of Air

On Ascension, have one person get the Banshee and the other person get the overshield and then stand at the Banshee spawn point. If the Banshee pilot boosts just at the right time when the other person jumps, the second person will be knocked off of the ledge through some clouds, then land on this solid patch of air. You can jump and walk a few steps on this but you can never get back except respawning.
