Captain Science and his young pal chase down a flying saucer sighting, and find not only a crashed saucer, but an almost-dead alien, who tells them why he is on Earth. For me the story is interesting because not only does it sound like the Roswell crash story (supposedly taking place in 1947, three years before Captain Science #1, from 1950), but it shows an early conception of what a flying saucer might look like. Like commercial and military aircraft the public were used to in those days, it has rivets.
The Grand Comics Database lists no writer, but credits Gustav Schrotter for pencils and inks..
Captain Science is more famous for featuring early artwork by Wallace Wood, also published in the first issue. Just click on the thumbnail.
