Phantom riding glitch

Halo 3
In the level Crow's Nest you can ride on of the Phantoms and it will take you out of the map.

Method
1. Jump on to one of the yellow clamps inside the hanger where you save a few Marines.

2. When the Phantom comes jump on top of it and grab one of the Plasma Cannons, (This is easier if you place a Deployable Cover on of the clamps).

3. Leave the turret while pressing back on the analog stick and jump

4. When you hit the invisible wall you will be pushed towards the middle of the Phantom, when this happens, get back onto the Plasma Cannon.

5. The Phantom will take you out of the map without getting you killed by the death barrier.
