Journeyman Elliot Langley: You are the last one.
Dan Vassar: No, you're wrong. There's one more.
Elliot Langley: Really, who?
Dan Vassar: I wish I could talk about it.
Elliot Langley: Wise man.

Hell's Kitchen Eddie Langley

Alias Sydney: You're scared. You should be. No one is coming to rescue you.
Rachel: I am an operative for the U.S. Government, so unless you want to start a war with the CIA, I would suggest–
Sydney: Here's your next problem, Rachel: we're CIA.
Rachel: Well, then this must be some... big misunderstanding. If you're CIA, we're on the same side.
Sydney: [to Grace] Call Langley and verify her story.
Rachel: You can't. We're off-book, black ops. Langley won't verify us.
Sydney: Well, that's convenient.

Alias Director Chase: I'm recommending to the board that you be stripped of classified clearance and assigned to the Dispatch Office at Langley.
Sydney: You're transferring me... to the mail room!?

Roswell Max: I failed. And my son... He's up there somewhere. I've just messed everything up. Langley's life. Yours. I'm so sorry, liz. I'm so sorry.
Liz: It's ok. It's ok.
Max: I'll never leave you, liz.

Alias Sydney: Did you study bomb diffusion at Langley?
Vaughn: Just seminar style. Nothing field specific.
Sydney: Does anyone ever learn anything at seminars?
Vaughn: Okay, let's just take this one step at a time. This is a charge of C-4. I can tell, 'cause it says "C-4" everywhere.

Neon Genesis Evangelion [repeatedly, quoting previous episodes]
Asuka #1: I'm Asuka! Asuka Langley Soryu! Charmed, huh?
Asuka #2: What are you, stupid?
Asuka #3: And now's my chance!
Asuka #4: [ripping her blouse open] Look at me, dammit, look at me!
[A sound effect of glass breaking]
Asuka: No, none of this is the real me!

Alias Sydney: [to Rachel] I want to tell you a story. Just stop me if I get something wrong. You were approached in college, someplace public – the quad or walking to class. A man asked you if you wanted to serve your country. When he told you it was for the CIA, you just, you couldn't believe it. But you took the tests, and they were easy for you; they made you feel good about yourself. You probably started work at a false front, some phantom company that had you doing entry-level analysis... Maybe you wondered why you were never sent to Langley. Maybe you wondered why you weren't being trained with other recruits. Then you got promoted.

Alias Sloane: I always knew there was something about you, from the first time I saw you.
Sydney: A lot can change in seven years.
Sloane: It's been a lot longer than seven years. I've known your father since 1971. I met him at Langley. I knew your mother. I went to your parents' wedding. Sydney, I've known you since you were a baby. I was out of the country for most of your childhood, various operations, but I kept tabs on you. I checked in on you in my own way. I always thought of you as my daughter, even from the beginning. Well, I just wanted to let you know...before you went away.

Job A Comedy of Justice by Robert A. Heinlein I knew that flying machines were impossible; in engineering school I had studied Professor Simon Newcomb's well-known mathematical proof that the efforts of Professor Langley and others to build an aerodyne capable of carrying a man were doomed, useless, because scale theory proved that no such contraption large enough to carry a man could carry a heat-energy plant large enough to lift it off the ground — much less a passenger.
That was science's final word on a folly and it put a stop to wasting public monies on a will-o'-the-wisp. Research and development money went into airships, where it belonged, with enormous success.
However, in the past few days I had gained a new angle on the idea of "impossible". When a veritable flying machine showed up in our sky, I was not greatly surprised.
