Listened to a podcast that described this submarine sitting in a Chicago museum. I believe subs are real, as evidenced here, but I’m not skeptical that they were nothing more than floating props. Allegedly the German navy had 1100 subs. These stories are full of magic numbers.
A child who toured the ship asked why all the labels on the ship were in English if it was built in Germany.
On June 4, 1944, a German submarine was prowling the waters off the West African coast for American and Allied ships. Part of a U-boat fleet terrorizing the Atlantic, this submarine was known as U-505. But on this day, the U-505 had just become the hunted.
Is this the predecessor to the ISS?
