A mysterious loud boom has been heard by Bensalem residents for years, with videos capturing the boom, which appears to also come with a flash of light.

Rick D’Aguanno, a Bensalem resident, told NBC10 that he has heard the boom and seen a flash coming from the front and back of his house.

“I definitely know that two or three came from the front, because I could see the flash,” he said, adding that another seemed to come from the back of his house.

Unusual noises and lights have neighbors in Bensalem concerned, especially since no one seems to know who is causing them. NBC10’s Deanna Durante has the story.

D’Aguanno’s cameras have also captured the boom and flash of light. The latest video of the boom was taken on Jan. 10, 2026, but recordings go back as far as April 2024.

D’Anguanno said that the boom and flash can be intense.

“I came up and saw the flash from all the different angles and it was pretty intense,” he said, describing a boom that occurred on Saturday. “We thought the van blew up or something out here in the driveway.”

Other Bensalem residents have taken to social media to report the mysterious occurrence as well. However, PECO told NBC10 that they were not doing repairs at the times of the blasts, and the Bensalem police said they have no major reports on the mysterious loud booms.

“It’s just very odd,” D’Anguanno said. “And then it’s like, how do these huge noises happen and there’s no answer for it?”
