Here is another underground factory, this one near Engels, Germany.This factory was tasked with building Heinkel 162s, a jet fighter built of cheap materials near the end of the war. The fighters were referred to as “Volksjaeger” with the idea that the aircraft would be easy to fly for new pilots, thought in reality the aircraft was very difficult to handle. This photograph shows tens of fuselages awaiting wings and engines.Only a few Heinkel 162s ever saw active service due to its late war introduction.
