I don't think the crew of the Jupiter 2 had a logo on their helmets. Imagine strapping in for blast off on the first launch, and your helmet says "Lost in Space."

"Hello, Mission Control, I just saw the helmets. What the hell does -"

"Now at X-minus 5. Check your systems.

"Hold on! We want an explanation of this, and we want it -"

"X-Minus 2, one . . . Zero. Main engine engaged."
