Flying Dumpster in Halo 3 - New Secret Vehicle

So these clever guys found out how to make a dumpster in Halo 2 fly. All you have to do is tip over a dumpster on its side and get two players to climb inside. After this you have to time your jumps in sync with each other and it begins to fly as you jump! Apparently if you get good enough at it then you can start to steer it around. lolz
