Not really! I found this great sight with a lot of fun U Boat myths, amazing what people will believe. On a side note, I new a lady that lived in northern California during the war, she 100% believed that Japanese American fishermen, were going out in their fishing boats and refueling Japanese submarines! I tried to explain that you measure submarine fuel by the ton not the gallon, and it would take a giant fleet of small boats to do so, and it was diesel fuel, which wasn't redly available during the war, she just said "I saw the flashing lights every night." Still, this sight is worth a good laugh! http://www.uboat.net/special/myths/
