Good Morning John T: I didn't know how much you wanted to know but I should have guessed that you would also like to know WHY. My understanding, back then with that F-4 antenna coupler, was that the dielectric of whatever is in the path of the current will play a big role. (you were on the right path) The compressed air AND fuel molecules make it harder for the electric current to get through regarding a sparkplug.. I'll suggest reading the Wikipedia on Dielectric. I'll add the link below (without errors?) By the way, a few other things I learned back then were that any sharp corners vs a smooth surface played a role. Sharp corners bleed off electric current into space quicker then smooth surface. On sparkplugs I always use a small 3 sided file to round off all sharp corners on the ground strap. The study of the spark in a sparkplug could be used as the begining for a study of thunderstorm lightening. Many of the same laws of physics apply.. and there is still a lot that is unknown.. even to a physicist. I always enjoy watching a good science program on TV that deals with lightening. By the way, that antenna coupler on the F-4 was an automatic tunning unit between any electronic item being used by the pilot and the antenn needed. Battle damage could be reduced with an antenna coupler to maintain electronics. Probably a $50k Black Box by now. Do you have a little better understanding of a "spark" now? Take care. ag. ret.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
