Now hear of Things that Flew.....over Chelyabinsk in Russia
on the 15th February 2913; the locals who witnessed it's
extremely bright appearance, also HEARD it's sonic BOOM
as it crashed and landed - apparently in a lake. Not withstanding, windows were blown in, doors blown off their hinges, 300 plus buildings were damaged and more that 1100 people were hurt by flying glass and from being hurled about by the force of the shock wave.
