THE FIRE CAME BY by John Baxter & Thomas Atkins

Dense little volume delves into THE RIDDLE OF THE GREAT SIBERIAN EXPLOSION! Loads of historical background, especially focused on Soviet hero scientist Leonid Kulik and his multiple expeditions to the devastated fall site deep in the blasted hinterlands of Siberia. The co-authors conjure up an out-of-control spacecraft's nuclear overload for some light science fiction on top of everything else. Recommended.
