You even seen those stealth bombers? You're not supposed to. Actually they are supposed to get by radar unseen so they won't get shot down.
Of course, the enemy will see a couple of pilots flying in the air. I guess that's enough to spook them out.
I remember they replaced those old planes that were to fly under the radar. Trouble was, they were flying at treetop level and some trees are taller than others.
By the time they switched to the stealth bombers, pilots were calling the old plane which sometimes hit a tree, "The Flying Bono".
