The reports of a low flying jet across portions of the Upper Peninsula Thursday afternoon prompted concerned residents to call 911.
The Negaunee Post of the Michigan State Police says the jet was spotted near Lakewood Lane in Chocolay Township just after 1:30.
There were also reports of a fighter jet over Coast Guard Point in Grand Marais in the same time period.
The FAA in Minneapolis was told about the jet, and said it was a Navy military aircraft conducting a training flight over water.
The FAA said the pilot did not violate any FAA regulations.
