Upside down !!!
Never noticed that at first until you said, ...bloody good spot.
Still a crime to actually do that I believe as well.
Technically, in this instance, it's correct. As flying the union flag upside down is a distress signal...
Is it not technically back to front as if you rotate this 180deg it would still be wrong?
Rotation about the horizontal plane, not the vertical plane, is required (in this instance) as Watshot says, because it's a distress signal
