while flying over a ground force of hundreds of thousands of your enemy? Yeah, good luck with that. That's the entire purpose that from day one of the quest, they KNEW it had to rely on stealth and secrecy...not announcing to the whole world by flying over it "here we are, and here's where we're going! But please don't prepare for us, we want to catch you off guard! Or, better yet, will you please close your eyes and ignore us so we can just fly over you?"
