In Impasse, I made a mistake in the name of the island on which the B-29 crashed. It should have read Østerskær Island, which is part of the Christiansø Archipelago, also known as Ertholmene. Perhaps the greater sin was in stating sovereignty belonged to Sweden, whereas in fact the island belongs to Denmark. My apologies.
A moment of luck, good or bad, often plays a greater part in our destiny than hours of design.
