Sonic boom as US fighter jets intercept plane that later crashed

US fighter jets scrambled at supersonic speed to intercept an unresponsive plane as it flew over Washington DC on Sunday.

The F-16 jets caused a loud sonic boom that was heard around the region, prompting concern from some residents.

They were deployed after the plane entered some of the most heavily restricted airspace in the country and failed to respond to the authorities.

It then crashed in a rural area of Virginia after a rapid descent.

Police and rescuers reached the wreckage near the George Washington National Forest by foot hours later and said no survivors had been found. Four people were reportedly on board. read more
