Residents across Maryland, DC, and Virginia reported hearing a large explosion around 3pm on Sunday, June 4. According to the Annapolis Office of Emergency Management, “The loud boom that was heard across the DMV area was caused by an authorized DOD flight. This flight caused a sonic boom. That is all the information available at this time.” A sonic boom is defined as a loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound.
According to Rueters, the Federal Aviation Administration reports that a Cessna aircraft crashed into mountainous terrain in southwest Virginia around the time the sonic boom was heard in the area and it is unclear if the two incidents are related.
