The Hanscom plane crash 911 calls were released Monday, offering grim new details about the mysterious and deadly incident.

Bedford Police Chief Robert Bongiorno made the audio recordings public two days after the private plane crashed and burst into flames while attempting to depart from Hanscom Air Field. Several people called to report the crash.


Caller: "Hi, something just exploded at the end of Fayette [Road]."

Operator: "Okay is there any fire?"

Caller: "There is fire… There was a big boom it shook the house."

Operator: "Do you see fire from your window now?"

Caller: "I do."

In the next call, a man named Mike Stephens says, "I think there was an air plane crash… There is a giant column of smoke and flames."

Another woman, who sounded shaken, said she looked out of her window and"all of a sudden I see this huge dome."

"It looked like the atomic bomb went off, and it was a mushroom cloud and fire was going everywhere," she said.

The National Transportation Safety Board is investigating the cause of the crash. A witness told investigators that the plane never left the ground.

All seven on board were killed, including Philadelphia Inquirer owner Lewis Katz.

The calls can be heard on the Bedford Police's blog.
