Astronaut Neil A. Armstrong, Apollo 11 Commander, inside the Lunar Module as it rests on the lunar surface after completion of his historic moonwalk.
The pioneering American is remembered as a humble hero; he's often described as a private man who was never comfortable with the public spotlight. When it came to tempting fate, however, Armstrong never shied away.
Before setting foot on the moon, the 38-year-old from Wapakoneta, Ohio, embarked on countless high-risk missions as a naval pilot in the Korean War and later as a test pilot for the National Advisory Committee for Aeronautics, the predecessor to NASA.
Here we take a look back at some of Armstrong's most daring moments.
