I'll just use the 'ole seat 'o the pants.
Here we go!
That’s best, anyway. If fuel is going to be in such short supply that I need to be shot out of a cannon, because liberal luddites quake in fear every time someone mentions the atom, I’d rather stay at home. Give me a nice powerful Orion class ship and I’d be happy to hop onboard with a seat-of-the-pants pilot. We’d get there quickly, and if Pluto doing what we thought it would be doing, we’d change course, catch up, etc., and not worry about running out of gas. The only way to travel!
