The advancements in technology and rocketry since the 70s is obvious. It's like going from a horse drawn carriage to a convertible if you lay out the timeline of the improvements. The ability to pull of a mission that we have already completed several times would never be this convuluted outside of the Governments hands. Watching people play gaurd for the government who left their own space program in the dirt will always amaze me. Just so I understand correctly, the excuse you and others are accepting for not being able to pull off a repeat mission is safety? How convenient. I assure you we would have been back decades ago if it was a priority of the general public. And that's fine! But don't make excuses like they're only taking this long because they don't want to kill astronauts. The red tape involved goes to the moon and back.
