Even stranger is another story included in this ebook: Beyond the Spectrum
This story describes a futuristic war fought with aircraft that carried what he called "sun bombs". These bombs were so powerful that with one brilliant flash of blinding light, one single bomb could destroy an entire city (much like a nuclear bomb ).
N. B.: When this story was written, airplanes were still tiny, dangerous machines that could barely carry one man and was decades before the Germans started their "heavy water" experiments, trying to construct a nuclear device.
In addition, this future war begins in the month of December when the Japanese stage a sneak attack on Hawaii.
It appears that the author was visionary of sorts.
