Aircraft get hit by lighting all of the time no big deal. We do a N.D.I of the strike area drill a .250" hole and fill it with a 1/4 AD rivet, I have seen holes as big as .500" we cut out the damage and put a repair doubler on the damaged area no big deal most aircraft fuselage is made out of 2024 T-3 and is about .036" thick very thin skin any Boeing 737 skin is .036" in the chem mil pockets and where the tair straps are at the skin on the aircraft would be no thicker than .072", a piece of the hair on your head would be about .002", so you can see that the skin of a aircraft is very thin. so aircraft skin at it thickest point is only about 36 time thicker then a piece of hair.
