It's very sad.
I would note also, though, that in terms of the heroism and greatness of the moon landing, there are many people; and in particular, I'd note John Kennedy.
Think for a minute what it takes for a new young president - the youngest in our history - to get the nation to sign on at the height of the cold war to do something simply great for mankind, when the incidental benefits weren't so obvious, to spend vast sums of our nation's fortune for the science and progress - the budget for the moon landing, a decade-long project, was as high as five percent of our national budget.
I think that was a great achievment politically for Kennedy, when it seemed fantastic to the people - only 20 years after the first flight of a jet engine, with almost no computers.
It's a stark contrast between the leadership of government then and now.
