7 JAN--This Day in US Military History

1948 – Kentucky Air National Guard pilot Thomas Mantell crashes while in pursuit of a supposed UFO.

Previously, the news media often treated UFO reports with a whimsical or glib attitude reserved for silly season news. Following Mantell’s death, however, Jacobs notes “the fact that a person had died in an encounter with an alleged flying saucer dramatically increased public concern about the phenomenon. Now a dramatic new prospect entered thought about UFOs: they might be not only extraterrestrial but potentially hostile as well.” However, later investigation by the US Air Force’s Project Blue Book indicated that Mantell died chasing a Skyhook balloon, which in 1948 was a top-secret project that Mantell would not have known about.
