Ask a Desert Storm F-117 pilot about how hard it was to fly to Bagdad undetected. To make things worse, the Iraqis knew the airstrikes were coming.

But in PI, those stealth missions really tested your skill.

The only one that really got me in PI was the second part of mission 14, where you infiltrate the enemy outpost near the Knossos, and that was only because I went out of my way to try to scan the cargo container for the bonus objective.  Completing just the main objective of that mission would have been fairly easy, and I managed to make it through mission 13's stealth setup on my first attempt.  Now, killing all of those turrets a bit down the pike...that's another story.
