Panicked 911 callers struggled to make sense of what they'd just witnessed after a Learjet went down in Florida, with one telling dispatchers a "bomb" had gone off, according to audio obtained by Fox News Digital.

The Learjet 60 departed Austin-Bergstrom International Airport at approximately 10:37 a.m. Nov. 1, headed for North Eleuthera Airport in the Bahamas. Shortly before 1 p.m., the aircraft went down in Palm Beach County, killing all nine people on board.

Moments after the jet slammed down just off a busy road, witnesses could be heard telling 911 operators they were trying to piece together what they'd just seen.

"There was an explosion," one caller said. "I think an airplane or rocket, something fell from the sky. We felt our house shake, and then we heard an explosion when we ran outside."

The caller compared the scene to a "bomb explosion," saying her power cut out for a few seconds before coming back on.

Stepping outside to look, the female caller said she saw sparks and smoke, telling the operator, "it was black, it was dark, like it was burning."

The calls came in at around 12:51 p.m., just after the plane crashed.

The woman thought at first that the loud boom could have been lightning, but noted she "didn't hear any, like, actual lightning sound either. It was like ... an explosion sound."

Heavy rain and thunderstorms were sweeping across South Florida when the Learjet went down, and federal investigators say the weather will be a major focus of their probe.

The National Transportation Safety Board announced Monday that the cockpit voice recorder was recovered.

"NTSB investigators have recovered the cockpit voice recorder (CVR) of the Learjet 60 that crashed on Nov. 1 near Greenacres, Florida," the NTSB said on X.

Federal investigators said the voice recorder was found at the location where the plane went down. It will be evaluated at the NTSB's Vehicle Recorders Laboratory in Washington, D.C.
