I feel like the Curiosity landing was planned by my five year old nephew:
Okay first we're going to just throw this at Mars. When we get there we'll use rockets to slow it down. A parachute will go *poof* but it's no good so then we'll launch another rocket from the rocket and it will fire MORE ROCKETS. But it's not going to land, it's going to just hover there and drop the thing down like a GI Joe out of a helicopter.
They should have named the thing "Occam would have a heart attack" and been done.
