Here is what Polish astronaut, Mirosław Hermaszewski, said about Armstrong death:
"A man passed away, but that what he done, will stay. Its a terrible news, I feel like i lost somebody close, cause he was really one of us. I had a chance to meet Armstrong, many times I meet with Buzz Aldrin and Michael Collins, therefore with all Apollo 11 crew. Its so unwaited message, because I followed current Armstrong's health state, and there was such a big hope after this surgery, that all is going to right direction.
Neil Armstrong was a wise and modest man, who realised, that he is first and will stay now in history of our planet forever. He was always very modest. People gone, but what they did (especially him) will stay forever. To the last days of our planet we will speak about Gagarin, Armstrong, because they was first man who leave the Earth and first who landed on other celestial body.
A man passed away, but that he done will stay. He already went to eternal orbit, but that what he done will stay with us on Earth to the end of the world".
