Fokker D.VII taking off
A crop-dusting plane that was used by Siegfried to destroy approximately 90% of the United States' the potato crops. In his guise as "Mr. Smith", Siegfried's Big "K" Corp. Dusting Service offered farmers free crop-dusting and then sprayed a bacteria capable of entering the potato by osmosis that would eat up the inside of the potato. Siegfried claims that he built the plane from a model kit sold by a company in Argentina (presumably run by former Nazis). Since the United States government refuses to pay the $10 billion ransom Siegfried planned to use the plane to continue to destroy the rest of the potato crop as well as broccoli, rhubarb, squash, and last but not least kumquats.
