ALT A large white airplane has a white rocket attached to its belly. A truck with a flight of stairs is pulled up to the forward boarding door, which is open. There is a band of blue running from the nose to the tail, just above the wings, and blue letters spell out “Northrop Grumman” to the left of the boarding door. A white tractor is hitched to the front of the airplane. The sky above is streaked lightly with white clouds. A person in a black shirt and pants stands under the wing.
