SARANAC LAKE — The jury is still out on what caused that loud boom Thursday morning, as officials from Barnes Air National Guard Base in Westfield, Massachusetts, say it was not their F-15 jets that caused the noise.

Shortly after 10 a.m. Thursday, the Saranac Lake region, including Paul Smiths and Vermontville, shook with a loud noise, which witnesses said knocked paintings off walls, shook houses and was audible over Zoom calls.

State Police Public Information Officer Jennifer Fleishman said troopers conducted an investigation.

“Several witnesses saw jets flying at the same time,” she wrote in an email.

However, the Vermont National Guard in Burlington, officials from the Fort Drum Army base near Watertown and officials from Barnes Air National Guard Base in Westfield, Massachusetts, have all said it was not their jets that caused the noise.

Eric Durr, a spokesman for the New York National Guard said there is not a plane in the state capable of producing a sonic boom.

Julie Avey from the public affairs office for the Barnes Air National Guard Base said jets from that base had two possible routes they were flying Thursday morning, one out over the ocean and the other on land, which she said could have taken them over the Adirondacks. But on Friday she said Lt. Amelia Leonard confirmed they did not fly over this area at that time.

No nearby earthquakes were reported by U.S. or Canadian geological agencies.
