Bob: I see you've made a shielded version of your solid rocket booster.
Jebediah: Yep. Hey Bill, how's it going in there?
Bill: Good so far, this feels safe.
Jebediah: It's OK, you can leave now. The ignition's started, there's no way to stop the launch.
Bill: Good. In that case, I'm running.
Bob: It's landed successfully. How?
Jebediah: No idea. Manned flight tomorrow!
