I've been reading this forum for a year or so, and I'm wondering about how the boosters are identified. For a given mission we'll learn that it's booster B1051 (or whatever) that's launching it. So my question is...when the rocket is on the pad and you're looking at it, how do you know if it's really that booster? It's not like they painted "B1051" or "NCC 1701" or whatever in huge letters on the side of it. Just wondering... Bruce.
