sonic boom

A loud sonic boom was reported across Norfolk as the fighter jets raced to intercept the airliner.

Nearby residents told BBC Scotland News the explosion sounded like a "sonic boom".

“It’s very stressful when you experience something like a sonic boom and you’re not expecting it,” said Phil Simon, a resident of Ojai for 25 years who spoke to the commission Wednesday.

The sonic boom — which has been known to startle people — happens when that booster breaks the speed of sound on the way down.

A few years ago, King became smitten with scratchy audio of the sonic boom produced by a meteor explosion over Russia.
