You are perfectly making my point spot on… If air is such a great insulator, what will prevent the lightening from jumping a 1” gap of a glass fuse?

Subject:  Air as an insulator ...
I seriously doubt this theory. Where I once lived just outside Chicago, Had an 4BTV with radials mounted on roof of house. Spring storms came around and I ran to basement to disconnect antenna while lightning was all around. After antenna was disconnected and coax was hanging 6 feet above basement floor, I watched a big, blue arc go from coax to basement floor.
Doubt that air is a good insulator.
