Quick mission transition

I'm trying to get a quick transition between a fly-down to a globe object and the terrain-based scene where action will take place. I figure it's easiest to simply have two separate missions and jump between them at the appropriate time. This seems to work well enough, but only when there is a bit of a delay between ending the first mission and loading the second. Here's the code that works:

function loadDefaultMission(%mission)
{
   Canvas.setCursor("DefaultCursor");
   createServer( "SinglePlayer", %mission $= "" ? $pref::mission : %mission);

   %conn = new GameConnection(ServerConnection);
   RootGroup.add(ServerConnection);
   %conn.setConnectArgs($pref::Player::Name);
   %conn.setJoinPassword($Client::Password);
   %conn.connectLocal();
}

function switchToTerrain() {
	Canvas.setContent( LoadingGui );
	endMission();
	schedule(100, 0, "loadDefaultMission", "disaster/data/missions/simple.mis");
}

However, if loadDefaultMission is called directly rather than being scheduled slightly in the future, the new mission will load, but also include the globe object from the previous one.

Am I doing something wrong here, or is this behavior expected?
