The 20-metre-wide space rock hurtled into the skies over the city in February and began to tear apart at an altitude of 28 miles. Travelling at a speed of 12 miles per second, the rock exploded with the energy of around 500 kilotonnes of TNT, researchers found. Directly beneath the meteors path, the shockwave was powerful enough to knock people off their feet. Windows were shattered in more than 3,600 apartment blocks, and a factory roof collapsed. Chilling account of the devastation caused by the meteor that exploded over the city of Chelyabinsk in Russia earlier this year which glowed 30 times brighter than the sun, leaving people on the ground below with skin and retinal burns.
