Among the topics that Wall covered were torture in Idi Amin’s Uganda, the sideshow town of Gibsonton in Florida, and the existence of a subculture of self-proclaimed vampires. However, it was on the old industrial island of Refshaleøen where she would encounter her most dangerous assignment yet.
At about 7:00 p.m. on August 10, 2017, Wall traveled to Refshaleøen, located just across the water from the Danish capital of Copenhagen. There, she met with Peter Madsen, a Danish inventor with a unique claim to fame. Back in 2008, he had launched a homemade submarine, dubbed the UC3 Nautilus.
Madsen had taken three years to build Nautilus, at a cost of some $200,000. And, at more than six-and-a-half feet wide and over 58 feet long, when it was completed it was the biggest submarine that a private individual had ever made. It was certainly an impressive achievement.
