"I'll tell you what, my boys. There are about 10 freight trains a day that rumble by my house, on their way to Chattanooga from Birmingham, AL.
They operate in one dimension, they travel 70 mph max and they are worth about one tenth of one O'Leary's jets. And they carry a crew of three. When they get down to one occupant we'll start talking about airliners....."
Huck- Actually trains operate in all three dimensions, backward/forward, left/right, and up/down would be the third dimension they would operate in due to mountianous terrain. Wouldn't want a runaway train now would we?
The fourth dimension, according to Rod Taylor in "The Time Machine" is, of course, time itself.
But we can save that discussion for some other time (can't believe I said that).
