Is that not a ship?

Aeroplane terminology and operating nuances all stems from Ships and shipping.
Port/Stbd/Rudder/Fin/keel/hack to stbd if a head-on, etc etc etc etc.
Even the Union Flag is allowed to be drawn the wrong way round on the Stbd side of a ship/aeroplane. For those that don’t know, as well as the “Fat white band being the uppermost at the pole”…..where no pole exists it is assumed on the left. OR, it is assumed at the pointy end of a ship and the nose of an aeroplane.
