As a specific example, C7\'s plugin could allow you to deploy a small (or large) satellite into orbit, and then land on the runway at the KSC just like the space shuttle. Well, okay, not just like the space shuttle, but close enough. I find that quite a bit more fun than parachuting into the ocean and having less control over my destination, and furthermore, not a cheat in any way. Now, if I were to do munar missions with a spaceplane, that just seems totally unrealistic and therefore not very fun to me. I wouldn\'t bother with it. As has been mentioned, you can\'t exactly cheat in a single player game, but it would feel gamey to me anyway. As far as competitions and challenges go, by all means, stick to stock parts or certain modpacks you feel are balanced. However, you can\'t expect every challenge to be stock parts only
