Detective H.A. Wasn't quite sure what to make of this hinge he spied underneath an adjustable seat on a plane.  At first glance, it looked like a regular hinge but with further investigation, he saw the leaves weren't in the same plane as they usually would be! What could cause this, he pondered, as he checked his notes on leaf orientations. With the leaves assembled reverse of what they normally would be, each leaf was on opposite sides of the pin instead of the same side. Why would someone do this? To allow for more rotation of the hinge? Or maybe they needed the offset between the leaves for the mounting? It was a bit of a mystery that might need more exploring.
