To get you excited about the new Captain Philip Strange book set to come out soon, we have a story from the fertile mind of Donald E. Keyhoe. This story has everything: An amazing new invention—smashing battles and cold-blooded murder high above New York skyscrapers—take-offs from catapults atop huge city buildings—parachutes coming to earth along the Great White Way. The first story of its kind and you’re sure to enjoy it!

We’ve posted several stories by Donald E. Keyhoe on the site and collected his Vanished Legion stories from Dare-Devil Aces into a volume as well as our new series of his Captain Philip Strange stories that ran for nine years in Flying Aces. The first of which appeared just a year after this story in August 1931.
