You're designing aircraft and spacecraft, dude. How super-powerful is that? You imagine them, you design them, you make it possible for them to exist—you figure out what needs to go where and how much fuel will be required to power them, and off they go.
However, those big metal machines are probably the only things you will have dominion over, unfortunately, and good luck getting them to pick up your dry-cleaning. But when those rockets kick in and the land starts to shudder, you'll feel the power, oh yeah, you'll feel it.
