5.07 pm.A blinding ball of fire incinerates everything within a 20-kilometre radius of the impact point.Beyond this range,the heat is still so intense that even up to 100 kilometres away,people in the street receive third degree burns.Only those lucky enough to be in the shadow of a building will escape burns.The shock wave from the impact will flatten trees and buildings up to 50 kilometres away.
