Nobody was injured in this spectacular natural gas powered bus fire, near Perugia, Italy, 16th April. Only the driver was on board. The columns of fire result from automatic vending of natural gas, intended to keep the fire away from the vehicle to give time for escape. In this case this caused the fire to spread to roadside woodland, where it was successfully extinguished.
