Several 911 callers reported hearing loud booms and seeing flames after the California helicopter crash that killed Kobe Bryant, his daughter Gianna, and seven others, according to audio released by the Los Angeles Fire Department on Monday.

Some callers reported either hearing or seeing an aircraft plunge into the hilly terrain of Calabasas about 9:45 a.m. Jan. 26, according to ABC 15.

One caller, a man, was walking on a trail when he heard Bryant’s Sikorsky S-76 chopper go down above him — mistaking it for a plane.

“I can hear this plane, I think it was in the clouds,” he told the dispatcher, according to the recording.

“We couldn’t see it — and then we just heard a boom, and a dead sound. Then I can see the flames,” the man says.

Another caller, at a nearby supermarket in Agoura Hills, reported to the dispatchers that a “helicopter crashed into a mountain.”

“We heard it, and I’m now looking at the flames,” said the man, who was about a quarter-mile away from the crash site.
