Pulp Magazine Cover, February 1948

This issue contains technical and scientific content rather than pulp fiction. The primary article discusses the Norton County meteorite fall of February 18, 1948 in Kansas and Nebraska. Scientists from the University of New Mexico's Institute of Meteoritics recovered fragments, including one discovered by farmer George W. Tansill. The meteorite proved to be an achondrite, an extremely rare type that supports the theory that the meteorite originated from the disruption of a planetary body with a lithosphere similar to Earth's. The article traces the history of meteorite classification into three groups—irons, stony-irons, and stones—and discusses theories regarding planetary disruption. The issue also includes Dr. Hynek's evaluations from Project Grudge, classifying UFO incidents by astronomical probability and alternative explanations, plus an article on space research featuring V-2 rockets and experimental aircraft.
