Today was crew module mock up day. First we routed power through the wall and ran velcro electrical cable lines up the walls. This eliminated the trip hazard and the mess of extension cords running through the hatch. We also made a reversible hatch door for the hatch. You mounted it outside and it a traditional hinge hatch like on a submarine. Flip it move it inside and it has the back frame and works as a plug hatch. The plan it to have the first flight vehicles use plug hatches, then we’ll move to hinged hatch.
