It IS rocket science

The old saying: It’s NOT rocket science. Means that not everything is complicated (ore need to be so). I realize that some things in life needs to be so, other words: It IS rocket science!
I think this is an wonderful way of changing the way in how to look at innovation: Why not take away the engine and use the rocket to power an helicopter?

The Dragonfly DF1 is a helicopter that uses rockets attached to the tips of its blades to power it instead of a conventional fixed motor attached to the body.
