Lieutenant, have this transmission switched to the linguistics section. Maybe those guys can work some sort of language.
gpt
Astronomy.
human
Professor, there's a ship right next door somewhere that should stand out like King Kong in a kindergarten.
gpt
I know, Admiral. I've been listening to the intercom. Our optical equipment isn't designed for close range work, but we've been doing the best we can, tried everything from infra-red through ultra-violet. If there is a ship out there I'm afraid it's invisible.
human
This is bad, Rogers. Mighty bad. Nervously, he walked across to the right of the bridge and stood, hands clasped behind his back, staring blankly out at blackness and the scattered stars.
gpt
I know there is a ship out there, and I know that a ship simply can't be invisible, not to radar _and_ optics.
human
What makes you sure there is only one, sir?
gpt
My God, Rogers, you're right! There might be ...
human
This is fire control again, sir. I think we've got something on the radiation detectors.
gpt
Good work, what did you find?
human
Slight radioactivity, typical of interstellar drive mechanisms, somewhere off to our right. Can't tell exactly where, though.
gpt
How far away is it?
human
I don't know, sir.
gpt
Thanks, he said,
human
This is the linguistics section, Admiral. The aliens understand a fairly common galactic symbology, I believe we can translate simple messages for you now.
gpt
Ask him where the hell he is,
human
He's laughing, sir.
gpt
Rogers! They _didn't know_ that we can't see them!
human
Look, sir.
