Reports of booming noises in northern Lee County and southern Charlotte County shook homes, and rattled some nerves.
"If it's a good one, it'll rattle the windows," said Chuck Brown, who lives in northern Cape Coral. He remembers hearing similar noises a few weeks ago - sonic booms from jets based out of the naval air station in Key West.
But the sounds he heard Wednesday morning likely weren't from the explosive speed of fighter jets - but actual explosives. The Collier County Bomb Squad told Fox 4 that they were detonating bombs in southern Charlotte County as part of a training exercise.
"I don't know what a bomb sounds like," Brown said. "But whatever went this morning was very similar."
Several weeks ago, sonic booms were believed to be a possible cause for the rear window of an SUV exploding in Charlotte County.
Brown said that he's not concerned the bomb squad training will damage his property, but said that the combination of sonic booms and bombs could get old if it became a common occurence.
"Was I overly concerned?" he said. "No, I wasn't, but if that's going to be a daily thing, that's a bit of a nuisance."
The Key West Naval Air Station told Fox 4 that their planes were conducting exercises again over the Gulf of Mexico, but that would not likely cause a series of multiple booms, as viewers reported hearing.
