Flipping a Phantom

The Sputnik Skull is necessary to perform this trick.

Go through the level until you see Wraiths attacking other enemies, then attack them so you don't die. Once you see a small tunnel with mini pillars,Combat form flood ride them, try to hijack one of them and destroy the other one. If you see little Sentinels attacking you or the flood forms,you will see a hole,go over it and you will see an empty part, maybe with a destroyed or a piloted wraith. Get out of the ghost and throw a frag or plasma grenade at the bottom of the ghost. Immediately get back in and you will be propelled to the higher platform. Once there, go to the mini bridge made of sand and go over it. After that go to the highest part you can get to and see the big area just after the steep hill. Go there, and in the left corner you will see a Phantom that looks like the Pelican that flips in Metropolis.Like that Pelican,it says "Flip Banshee"

In halo 3, on the level crow's nest, in the hanger where u must clear it for the pelican to launch, the phantoms that drop off the troops can be boards by jumping into its troop bay. using one of its plasma cannons while it flies out of the map will result of it mysteriously dropping. you might be ejected upside down while it is tumbling, but the phantom is flippable (no hold rb to flip...)
