There is a good thing you can do if you're a man on the carrier. Walk to the front of the bridge and climb up the rigging. There's a small, inconspicuous door labelled "Padraic Willoughsby and Co." just near the top. Bang on the door with your rifle. On February 29th of every leap year, the door will open and there will be a small tankard of cold beer. Drink the beer. At the bottom, in nearly illegibly small type, it says "The blood of the innocent." Throw the mug at any plane trying to respawn on the carrier. If you hit one, a second door will open to a small wood panelled room. The door will instantly unlock. Inside there is an empty room with white walls. No light reaches this room, except for a small sliver from the other end of the room. When you approach this room you will find that it is actually another door. When you knock on it, a voice will ask "What makes a man become exalted?" If you respond with the phrase on the bottom of the beer mug, the door will open and you will come into another room. Inside it you will find small models of each plane in the game. Smash each one with your rifle butt and the corresponding planes in the air will burst into flame and your team will Win.
Just ask Slenderman.
