“Contrails (short for “condensation trails”) or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets or, if the air is cold enough, tiny ice crystals”. – Wikipedia

“Josephine Baker (June 3, 1906 – April 12, 1975) was an American-born French dancer, singer, and actress. Nicknamed the “Bronze Venus”, the “Black Pearl”, and even the “Créole Goddess” in anglophone nations.

Baker was the first African American female to star in a major motion picture and to integrate an American concert hall, and to become a world-famous entertainer. She is also noted for her contributions to the Civil Rights Movement in the United States (she was offered the unofficial leadership of the movement by Coretta Scott King in 1968 following Martin Luther King, Jr.'s assassination, but turned it down), for assisting the French Resistance during World War II and for being the first American-born woman to receive the French military honor, the Croix de guerre”.
