This might be a picture of flying saucers taken at night over Arizona or New Mexico. It was in fact taken in Dr. Menzel's laboratory at Harvard University. # THE TRUTH ABOUT FLYING SAUCERS One of America's leading astronomers goes into his laboratory at Harvard and disposes of the flying-saucer myth. He adds simple instructions for making flying saucers in your own kitchen By Dr. DONALD H. MENZEL Donald H. Menzel is professor of astrophysics and associate director of solar research at Harvard University. His work on flying saucers was done in response to a request from LOOK. The Air Force has expressed a lively interest in it. I SUPPOSE that I should be especially well qualified to write about flying saucers since I happen to be one of the few persons who has actually seen one. My solar studies take me frequently to Colorado and New Mexico, and I was at the Holloman Air Base, near Alamogordo, N. M., at the height of the flying-saucer scare. That very morning, I had glimpsed what seemed to be several saucers moving overhead-until I focused my eyes more clearly and recognized the objects as weather balloons. That afternoon, I expressed my belief that most of the saucers could be thus explained. But others in the group--including several well-known scientists-indicated that there was probably more to the saucer story than that. Early that evening, I had my second attack of saucers. I was in the back seat of an automobile, being driven toward Alamogordo and admiring the full moon as it rose over Sacramento Peak toward the east.
