How in the hell did you get a helicopter to work in Mars' almost non-existent atmosphere?

Chernobyl and Fukushima are not ridiculous examples of how things can go bad.

The technology to prevent BOTH incidents existed at the time of construction of BOTH plants. They were not used. At Chernobyl, it was cheaper to not have a containment dome over the reactors. That's an economic decision based on lack of resources. At Fukushima, they did not anticipate a tsunami of that height to come into their plant, the redundant backup systems were susceptible to the exact same faults, and they failed in the same way.
It's not that we CAN'T make it safer. Wejust don't BOTHER to make it safer.
