A large block of ice fell from the SKY and crashed into a stunned family's back garden where it has left a massive crater. <br /><br />The rock struck the garden of the Helliwell family with a "big boom" and shook their home yesterday morning (Tues). <br /><br />The impact caused a crater measuring 1.4m by 1.2m (4ft 7in by 3ft 11in) in the middle of their lawn with bits of ice scattered across the grass.
