During the second world war, the Calvé Peanut Butter factory in Delft was equipped with anti-aircraft weapons which they bought themselves to protect the factory. Employees could volunteer for the 'Voluntary Landstorm Corps Anti-Aircraft Service', to be trained by the Ministery of Defense as anti-aircraft gunners. On the 10th of may, the first day of the war, they shot down a total of eleven german airplanes. The factory did not need to cease production. dont mess with our fucking peanut butter.
