Meh i found this the day i got bf2. Be the CIS on any space map and fly over to the republic hanger. Then land it indside and take off with one of their ships. Almost as soon as u take off, land. If you do this just right u will get outside of the shield that wont let you out if you walk up to it. If done right you should now be on a ledge outside the starship that goes all the way around it. If you jump off it takes forever to die, but it is cool to see the ships fade away.
