What happened to the multiplayer game on facebook where you could fly airplanes with other people and shoot?

Well I got a facebook today and I remember this awesome airplane game I had seen my step dad playing on facebook. It is with other people and you get to shoot other people down. I remember searching it on the facebook search in the corner and I guess they took away this game? Can someone tell me what happened to this awesome game and if it is playable anymore?|||when you search for it, click see more or else they might hide it, even if its more popular that other applications for some reason.
