Kerbal Space Program

The MEM lander can's attitude reference is backwards and should be rotated 180 degrees around it's roll axis. As a comparison, the attached screenshot shows the default attitude of the parts in reference to the their flightball orientation when controlling them. If you were to adjust the attitude of the MEM while observing the outside surroundings from the IVA, you would experience the opposite orientation movement than you would expect.

The effect is opposite yaw and pitch changes than what is expected compared to other command pods
