Stratosphere And Rocket Flight (Astronautics).

The first British book on space travel by a science writer, and one of few books in English before WWII with Lasser (1931), Monk (1933), and Cleator (1936) all also available in this collection. This first edition sold out within a few months, prompting a revised and enlarged second edition later the same year, also in this collection. Philp also surveyed the field two years later in “Where Is Rocketry Today?”, Popular Aviation, October 1937, also in this collection.
