I tease a coworker about the Musk/Bezos rivalry. This is a great opportunity to send him a quick email saying, "Oh, look! Bezos wants to blow up a rocket in order to show Musk how to blow one up right!"
Heh.
Actually, I'm beginning to wonder if all this rocket wizardry is in vain. If the Em Drive actually pans out, it could make this kind of tech obsolete in fairly short order!
