Are unlocked planes available for use in Campaign Mode? Thanks !!!

I've got it on wii but yeah unlocked planes can be used in campaign

Thank you, jordanandy. I also have the Wii version and it makes unlocked planes available for Campaigns. However, the XBOX360 version that I have does not appear to offer a hangar menu prior to starting a campaign. I get stuck with only the default plane. If anyone out there has the XBOX360 version, please tell me if using unlocked planes in campaign is possible & how do I do it. Thanks!!!
