Why does the object rotate when I move the object?

I have a spaceship. When I try to move it, the object rotation changes on the game view but not in the hierarchy( rotation values (0,0,0)). For example when I try to move right the spaceship rotates left a littlebit.

Those pics may help


Uhm… Nope. It does not rotate. Decrease the scene window field of view or just decrease its width in the editor and see that now it seems like it ‘rotates’ less. However, as I said, it actually doesn’t rotate at all. It’s just an optical illusion caused by the wide field of view of your scene window camera.
I can see that the ship at the second screenshot still looks straight forward.
