Michelle Jones: You know, Susan Yang thinks you're a male escort.
Peter Parker: What? No! Of course I'm not a male escort.
Michelle Jones: Well then you're Spider-Man.
Peter Parker: MJ, I...
Michelle Jones:...am Spider-Man?
Peter Parker: No. Of course not!
Michelle Jones: I mean it's... kind of obvious.
Quentin Beck: Don't ever apologize for being the smartest one in the room.
Nick Fury: Uneasy lies the head that wears the crown. Stark said you wouldn't get that because it's not a Star Wars reference.
Nick Fury: How's the suit?
Peter Parker: It's a little tight around the ol' web-shooter.
Spider-Man: Excuse me, sir! I can help! Let me help! I'm really strong and I'm... sticky!
Flash Thompson: Yo, Parker! This is called an airplane. It's like the buses you're used to, except that it flies over the poor neighborhoods instead of driving through them.
Peter Parker: What's your password?
Happy Hogan: Password.
Peter Parker: No, what is your password?
Happy Hogan: Password. The word spelled out.
Peter Parker: You're head of security and your password is "password"?
Happy Hogan: I don't feel good about it either.
Mysterio: It's easy to fool people when they're already fooling themselves.
Peter Parker: Everywhere I go, I see his face. I just really miss him.
Happy Hogan: Yeah, I miss him too. I don't think Tony would've done what he did, if he didn't know you were gonna be here after he was gone.
Nick Fury: We have a job to do, and you're coming with us.
Peter Parker: There's gotta be someone else you can use. What about Thor?
Nick Fury: Off-world.
Peter Parker: Doctor Strange
Maria Hill: Unavailable.
Peter Parker: Captain Marvel.
Nick Fury: Don't you invoke her name!
Peter Parker: I'm just your friendly neighborhood Spider-Man.
Nick Fury: Bitch, please! You've been to space.
Happy Hogan: You take care of the suit. I'll take care of the music.
[AC/DC's "Back in Black" starts playing].
Peter Parker: Oh, I love Led Zeppelin!
Mr. Harrington: Did I tell you how my wife pretended to blip out? Turns out she ran off with a guy in her hiking group. We had a fake funeral for her and everything... Well the funeral was real. 'Cause we thought she was really dead.
Mysterio: If you were good enough, maybe Tony would still be alive.
Peter Parker: How could you do all of this?
Quentin Beck: You'll see, Peter. People... need to believe. And nowadays, they'll believe anything.
Happy Hogan: I'm in love with Spider-Man's aunt!
Answer: They are shown descending down from a satellite. It's reasonable to say they return to space when not in use. And also they can just encase themselves in more illusions to stay hidden regardless of where they go.
