Suppose The Apollo 11 mission was the first manned mission to land on the Moon on July 20, 1969. The crew, consisting of Neil Armstrong, Buzz Aldrin, and Michael Collins, successfully completed the mission and returned safely to Earth. Neil Armstrong became the first person to walk on the Moon, followed by Buzz Aldrin.
Can we infer that "Apollo 11 was a failed mission."? Yes, no, or maybe?
