Within this book, the Americans were island hopping on the islands they controlled, trying to get closer and closer to the Japanese mainland. But it was the islands they controlled them. Some islands were unfit for aircraft runways as being too short. This caused the Americans to either improvise, by adding materials into the ocean to lengthen the island, or to not use it at all. Another difficulty these islands possessed was the distance between them. Between American controlled islands and Japanese controlled islands, were vast amounts of water infested with sharks.This proved to be dangerous since the long distance meant a higher chance for an engine failure, especially with the B-24. Pilots could also get lost since all they saw was water, resulting in many lost airplanes. It was said in the book that for every man who died from Japanese attacks, 5 men died from the bomber
