I was holidaying on Menorca recently and I was in an 8th floor hotel room. My balcony had a sea view. One day I stood on my balcony and i could see, quite clearly, a cruise liner. I ran down to the seaside and, alas, the cruise liner had gone "how odd" i thought. Back on my balcony the cruise liner appeared again. I repeated this test 5 times, so it was a "fair test".
Distance from balcony to seaside <100 metres.
Question - where did the cruise liner go?
