Source of Sonic Boom Identified

The “boom” heard around northeast Missouri on Monday afternoon has been identified. The two loud booms were caused by a supersonic plane. The The Whiteman Air Force Base said the noise was likely caused by a Boeing aircraft on a test flight from its St. Louis factory. The sudden loud booms rattled a number of people enough to call the police. The Kirksvillle Police Department recieved at least 20 calls Monday afternoon – mostly from residents in the north end of the city.
