can barely remember attending, much less any of the course content.

Heck, Rich, you were playing "Rock, Rock, Rock," before paper and scissors
had
been invented....

As a teacher's assistant, it was my job to keep the candles lit during the
lectures.

Down here in the soup, the mass to expel backwards is free. On the moon,
though, you have to bring that mass with you.

So...how much air, in mass, are we talking about?

Lots free photons floating around, though. Do photons have mass? Even a
little bit? If they do, couldn't we collect them in the front, accelerate
them until their mass becomes ~ infinite, then toss them out the back?

Heck, come to think of it, we don't even need protons. If mass increases as
velocity closes in on C, all we need for reaction mass is a handful of
depleted uranium. If we can toss it away fast enough. I don't suppose that
..50 caliber hawgleg that Ammeter carries would do it. We need a railgun or
two.

P.S. I like that idea about recycling boomers!
