McMurdo/Casey ops with 747-400 plus some polar games...

Hi all,First for the games: I took off in Thule the other day, with a routing direct NPOLE (it's in the FMC database). All goes well until... N89 30.0 (about 30NM from the north pole). That's as close as FS2004 will let you get to the pole. From there on, it's flying circles! The FMC spewed two messages as well, the first one was something about IRS separation, the second one said IRS POSITION ONLY. Guess the GPS don't work up there.... (well, presumably the GPS position is taken from the FS2004 internal calculations, which mess up approaching the pole).I'd expect the same to happen at south pole so I didn't even try. I heard that's fixed in FSX? Any experiences anyone? Is the ice runway at South Pole modelled?As some of you may know, the Australian Antarctic Division is building an ice runway near Casey station. It's going to be robust enough to hold a fully loaded 747-400 (that's obviously not going to fly there, but C-5's will). So just out of curiosity, I went down to McMurdo and flew a few (manual) circuits, which was very testing! The weather was crap and I essentially had to set myself up with dead reckoning only, but it worked!Does anyone have those runways for the FMC? Also, most navaids appear to be missing down there.Cheers- Balt
