Fly,mastercheif, fly!!!!
In multiplayer mode select a map with the banshe and warthog.
In the level place the banshe next to the warthog and have your plasma sword lock on to your friend, then sit in the passenger side of the warthog and have your friend enter the banshe.
Make your bud fly as far as possible then exit the warthog and you'll fly staight to the banshe!
P.S.keep the camera on your bud the whole time.
