Snuck into the hangar museum in Wichita and the static display LRU rack taught me more than 3 days of class
I was killing time in Wichita at the little aviation museum near the airport and they let you walk right up to an old jet's avionics bay. Seeing the actual tray, connectors and wire routing in the metal, not a slide, made the pinout stuff finally click for me. Am I the only one who learns better eyeballing a real rack than reading the manual?
