My hero. These men were so brave and I agree with tdracer: soon we will not have then left on Earth with us. When I was 17 years of age, I wrote to Commander Cernan, at NASA, telling him how much I admired him and all of the NASA astronauts who went to the Moon. I was stunned that I received a handwritten reply from him. He had passed my letter around to his fellow astronauts, as well as his co-workers at NASA. He was so grateful that I had written. I still have the letter.
