A random captain the other day: "Welcome to *insert ship name here*. You shall be my crew today, and as you can see the flight weather is quite clear and the view the usual hopeless wreck. Feel free to use the upper left field gun at your leisure for sniping. Engineer X, please make sure the upper deck is fixed while mr. Y applies his skills on the lower deck. Mister Wilkinson, do make yourself comfortable on the main gun and all of you enjoy the flight. Let's shoot some ships."
Not as awesome as above mentioned ones, but it did set a certain atmosphere for the match. ^^
And this thread is becoming stuff of Glorious Quotes by itself. xD
