Rubye Berau (1931 - 1977) was a pilot and member of "The Squadron of Death," (S.O.D.) an all-female group of student fliers based at Akron Airport in Ohio that performed in the 1930s. By 1934, the squadron would have 13 members who would always fly on the second Friday of each month, and, if possible, on a Friday the 13th. The squad's lucky number was 13, their insignia was a skull-and-crossbones, and their mascot was a black crow named "Soddie." They also wore helmets, goggles and white jumpsuits, and some stories recount that they even wore high heels while in the air.
