Goodnight coub

The word "Goodnight" appears in large, white, outlined letters over a black-and-white background of a cloudy sky, with the text fading in and out. As the word fades, a formation of vintage military aircraft flies across the screen from left to right, moving from the upper left to the lower right, before the scene cuts to black. The text "History_Of_Warfare" is visible at the bottom of the screen throughout.
