B-17 Flying Fortress

The Boeing B-17 Flying Fortress is an American four-engine heavy bomber aircraft.

Call of Duty: United Offensive
In the level Bomber, the player is a crew-member aboard a British B-17. In this role, the player must man the dorsal, tail and port waist guns of the B-17 at various appointed times to fend off attacking German BF109s; first with the aid of Spitfire fighter cover, then without. The player is also tasked with shutting off the fuel lines to put out engine fires, and cranking open jammed bomb bay doors. Throughout this mission, several B-17s in the squadron are shot down, and the player's B-17 takes a terrible beating from flak and fighter attacks, with substantial battle damage accumulating on the Flying Fortress and its crew. Eventually, the player's B-17 comes to grief and the player must bail out to end the mission.

Call of Duty: World at War
In Call of Duty: World at War, B-17s appear in the Japanese campaign during the mission "Hard Landing". After the player acquires the M2 Flamethrower and successfully destroys and exits the Japanese pillbox, numerous B-17s can be seen flying high overhead. One unlucky B-17 that has been stricken by Japanese anti-aircraft fire flies directly over the player, clips a palm tree, and crashes into the nearby airfield. The crashed B-17 can later be seen up close when the player's squad arrives at the airfield to fight the occupying Japanese force. The B-17 was also going to be a fourth killstreak in multiplayer, but was scrapped along with the other fourth killstreaks.

In the intro to Call of Duty: World at War's Nacht der Untoten, it can be seen in the background. This same crash site is visible from upstairs on the level, near the Sniper Cabinet. This can also be seen in the Call of Duty: Black Ops version of Nacht der Untoten.
