In 1938, Wallis tried to join the RAF again, this time with the newly formed RAF Short Service Commission Scheme, but again failed the eye test. In 1939, he was called up to RAF Uxbridge, and again was sent for a medical. When it came to the eyesight test he managed to pass, as Wallis later recalled, "I did the first line with my good eye then they covered it up and asked me to read the bottom line with my bad eye, without them realising I just turned my head slightly so I could again see with my good eye—I passed it with Above Average Eye Sight!"[4]
