SIOUX FALLS, S.D. (KELO.com) — Residents across Sioux Falls on Monday may have noticed two white, stationary objects floating in the evening sky.
While the objects may have been mistaken for some sort of alien aircraft, the National Weather Service in Sioux Falls says they were stratospheric research balloons released by Raven Aerostar.
The balloons were launched from the company’s research facility near Baltic.
