Thank God it goes down the toilet with the J model. You learn the ops limits you need and you don't fill your head with useless herc trivia. Feel free to learn the construct of the 1553 data bus and desribe the path of electron from a BAU to the MC, but do it in private, don't bore the crew.

Don't get me
