Explosion-Like Noise Heard Across D.C. Area Was a Sonic Boom, Officials Say Sonic Boom Heard Across D.C. Area Was From Military Jets, Officials Say
(32 minutes later)
A loud noise that was heard across much of the Washington, D.C., area on Sunday afternoon, including in the suburbs of Virginia and Maryland, was caused by a sonic boom from an authorized Defense Department flight, the Annapolis Office of Emergency Management said. A loud noise that was heard across much of the Washington, D.C., area on Sunday afternoon was caused by the sonic boom from military jets scrambling to respond to an intrusion into restricted airspace by a private flight, military and U.S. officials confirmed on Sunday.
It was not immediately clear where the flight originated, what its purpose was or which branch of the military was operating it. “That is all the information available at this time,” the Annapolis agency said on Twitter. At least two fighter jets were scrambled from Joint Base Andrews, after a Cessna entered restricted airspace over the D.C. area, prompting the emergency response to intercept the flight, the officials confirmed on Sunday.
A little after 3 p.m. on Sunday, people said on social media that they had heard a loud boom in Washington, D.C., and in Maryland and Northern Virginia. Many said the noise sounded like an explosion, and some said the boom was so strong that it shook their homes. After the Cessna veered into the restricted area, which protects important national landmarks, the Federal Aviation Administration called the pilot but received no response from that plane and the military ordered the jets to intercept, a military official said.
Officials later determined that the Cessna did not pose a threat and the investigation would look into why the pilot did not respond to the F.A.A. The Cessna was not shot down, the officials said.

A sonic boom is caused by an object moving faster than sound, or about 750 miles per hour at sea level.

There was another incident involving an aircraft in the vicinity of the Washington metropolitan area on Sunday, though it was not immediately clear that the two events were related. Later, the Federal Aviation Administration said that a Cessna Citation, a type of business jet, had “crashed into mountainous terrain in a sparsely populated area of southwest Virginia,” near Montebello, around 3:30 p.m. local time.

The noise from the sonic boom startled people across the Washington area and many took to social media to speculate about what could have caused it.
Rafael Olivieri, 62, said he was at home in Annandale, Va., when he heard a “loud, very short sound” that shook his house. Mr. Olivieri ran outside, where his neighbors were also trying to figure out what had happened. “My first thing was looking to the sky,” he said. “I was really worried.”Rafael Olivieri, 62, said he was at home in Annandale, Va., when he heard a “loud, very short sound” that shook his house.
