 So, what we're doing right now is drilling on different types of metals, trying to get spacing and line-ups for putting in rivets or what we call composite locks. So we're building the frame of our aircraft. It's not going to be loose. Lines are going to be straight and tight. It encompasses many different types of fasteners, many different types of material including titanium, a crest, which is stainless steel and aluminum. This is a relaxed space. Make sure that you're knowing every little basic detail you need to become a much better mechanic. I want to make sure that whenever they actually go back to the fleet they have a better grasp on manufacturing, belt manufacturing best practices that they can apply to their daily tasks. Every single thing that I've taken from the school that we haven't learned yet or even information on tools that maybe the Marine Corps doesn't know about, I'm going to try and push that information out to my squadron and all my junior Marines. The more people that learn the information here and they're willing to pass it on, the more people that can benefit from it.
