The Nazi Zeppelin, the Luxembourg toured America in a "gesture of friendship" but was actually secretly assisting Sinclair's mission. It appears overhead to evacuate Sinclair and his associates, who orders their prisoners shot. Suddenly, FBI agents announce their presence and both they and the gangsters find themselves joining forces to battle the Nazis, but Sinclair and Lothar escape with Jenny aboard the Zeppelin. Cliff uses the rocketpack to reach and board the Zeppelin, but during the ensuing showdown Jenny accidentally sets the craft on fire with a flare gun. Sinclair takes the rocket to save himself, but not before Cliff thumbs off the chewing gum patch; with the leaking fuel ignited by the exhaust flame, Sinclair dies crashing down upon the last four giant letters of the "Hollywoodland" sign. Lothar is engulfed in flames as the Zeppelin explodes and crashes.
It was patterned after the LZ 129 Hindenburg and its sister ship, the LZ 130 Graf Zeppelin. These great passenger ships are over 800 feet long. The Hindenburg's exploding and crashing in 1937 is what the Luxembourg's destruction is loosely based off of.
