Narration
A blinding blue fluorescent light surged head-on through the Illinois night sky.
May 29, 1950 — an American Airlines airliner cruised east of Mount Vernon, Illinois.
Captain Willis Sperry watched the object halt dead and loom as a dark submarine silhouette.
Silhouetted against the full moon, the dark metallic hull revealed no wings, no fins.
Sperry's formal report entered the 1950 wave of aviation UFO cases and was filed away.
The instant Sperry banked to pursue, the submarine-shaped craft vanished into the Illinois night forever.
