McCandless orbited Earth for 1 hour and 22 minutes, captured in iconic photos by Robert "Hoot" Gibson, and his famous quip referenced Neil Armstrong's moon landing. McCandless passed away in 2017, and his MMU is now on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center in Virginia.
