4. Jodhpur Boom: Unexplained Sounds in India and Across US
What was described as a “sonic boom” shook Jodhpur, northwest India, on Monday Dec. 17, 2012, at 11:25 a.m. Sonic booms are caused by the shock wave generated by an aircraft moving at supersonic speed. It sounds much like an explosion. The precise source of the boom in Jodhpur, however, remains a mystery.
Defence spokesperson Colonel S.D. Goswami told Times of India that the army did not know the cause. The army would not engage in activities that would cause a sonic boom so close to populated areas, Goswami said, because it is against regulations; it could cause damage.
