As we know,charged clouds(from which lightning stroke initiates)may be charged with either +ve charge or -ve charge. Now say one cluster of cloude is fully charged with +ve charge & another cluster is fully charged with -ve charge. In the sky these two cluster of charged clouds have come in such a distance that, if they come clouser by some few yeards then the lightning discharge will take place between these two cluster of clouds. Under such a situation an Aircraft came inbetween. what happend??
