Charles Kingsford Smith
In 1917, Smith's plane was shot down during battle. He survived, but was injured and had to have part of his left foot amputated (removed by surgery). He received the Military Cross for his bravery in battle. Because of his injuries, Smith was made an RFC flying teacher.  He was also promoted to Captain.  In April 1918, Smith was assigned to the Royal Air Force, which had just been created.
