By the late 1950s, airplanes were a fairly common sight over Des Moines, but not quite like this. On January 29, 1957, Roy Soderquist took a Cessna 172 from his flight instructor and spent the next several hours flying low over downtown Des Moines. He managed a crash landing in a field, with little injury to himself and the plane. Charges against him were dismissed.
Though it has been widely believed that the first night professional baseball game under lights was played in Des Moines on May 2, 1930, it appears that this is not entirely accurate. The Des Moines Demons did indeed play the first game under permanent lights on that date at the Western League Park at Sixth and Holcomb.
