Why can't you fully unlock stuff through single-player?

You are, Iz izz posting (in Australia, so no idea what 9pm East Coast time is - hopefully not far away!) and then jumping on

But in terms of the unlocks, a lot of people like flying the different planes, particularly on sim where you can really tell the difference, and training mode can be a lot of fun - half the missions are dogfights to a degree, and most of the online is dogfighting or bombing, all of which you can do in training as well . I could just see me being a bit miffed if I wasn't online, and could imagine there will be people out there who are (who we won't see around here - and there are a _lot_ of gamers, the vast majority, who don't visit forums).
