|A young air force officer had a very beautiful wife. Early each morning he left his house and went to the airport, and an hour later his wife always left the house too, with a big white towel, and went for a walk on the beach.|
Her husband always flew over every morning, and when she saw his aeroplane, she held the white towel high above her head. When her husband saw it, he made either the left wing or the right wing of his aeroplane go down.
The left wing meant: I will be busy tonight and won't be home.
The right wing meant: In eight hours I will be holding you in my arms.
One morning he flew over with eight other aeroplanes, and his left wing went down. Before his wife had time to feel sad about this, all the other aeroplanes flew over, and each one of them turned its right wing down.
