A former client of Dean's calls him up when a plane crashes under mysterious circumstances. Dean and Sam must board an endangered flight to save the other passengers.
Near the beginning, when Sam and Dean are talking, if you look close you can see Sam chewing on something. But, we never see him eat anything. It is revealed on the commentary by Jared and Jensen that they had Sam eating a donut, but they never got the donut in the shot. So, it appears that Sam is just chewing on nothing.
Why are none of the passengers alarmed by the shouting and snarling coming from the room the co-pilot just went into? They would definitely hear what was going on, the only thing between them is a thin curtain.
"Cristo" is not Latin, but the Greek Χριστός (Christós) translated as "The Annointed One". The Latin word for "God" is "deus" or "deo." Both "deus" and "deo" are heard when performing the exorcism.
When Sam and Dean got to the airport Sam said they had half an hour to get on the plane because the plane left at 8 PM. But earlier when they were in the car he said that it was a five-hour drive and they would never make it in time. That would make it 2:30 in the afternoon but when he said that it was dark outside.
The twin-engine plane had the registration number C-GBBP when it was on the ground. In flight, it was shown as C-GUTV.
Trivia: The song that Dean is humming to calm himself down in the plane is called "Some Kind of Monster" by Metallica.
If you watched the version of this episode that aired on December 13, 2005, you heard the number they showed in closed captioning for Dean's cell number. They changed it from the original airing. They also changed the message you will hear if you call the original number that John said. If you call 866-907-3235 now, you will hear "Dad? We really need to hear from you. Leave me a message, text me, check your jwinchester1246 email. Anything. We have new info. "
When you actually call Dean's 866 number given on this episode, you'll get the following message: "This is Dean Winchester. If this is an emergency, please leave a message. If you are calling about 11283, page me with your coordinates." 11283 is the date of Mary Winchester's death.
On the closed caption, they listed a different phone number with the area code 785, instead of the 866 number. The area code 785 is from Kansas, which is where the characters are originally from.
In the dialogue for this episode, they give an actual (toll-free) number for Dean's cell phone: 866-907-3235, rather than one of those unreal 555- numbers. However, in the closed captions they do give a 555- number, 785-555-0179. Presumably the original script, from which the caption text was derived, had the 555- number but then they changed it for the actual on-screen dialogue.
Dean: Maybe the thing's just not on the plane.
Sam: You believe that?
Dean: Well, I will if you will.
Dean: Yeah, a middle-aged dentist with an ulcer's not exactly evil personified.
Sam: Homeland Security. It's pretty illegal, even for us.
Dean: Yeah, well, it's something new. You know, people haven't seen it a thousand times.
Sam: You've been in there forever.
Dean: You can't rush perfection.
Sam: What is that?
Dean: It's an EMF meter. It reads electromagnetic frequencies.
Sam: Yeah, I know what an EMF meter is. But why does that one look like a busted-up Walkman?
Dean: (proudly) Because that's what I made it out of. It's homemade.
Sam: Yeah, I can see that.
Dean: What time is it now?
Sam: Oh about 5:45.
Dean: In the morning?!?
Dean: (sarcastically) Where does the day go?
Sam: Yeah, he told me. It was a poltergeist?
Co-Worker: Poltergeist? Man, I love that movie!
Jerry: Hey, no one's talking to you. Keep walkin'.
Demon in co-pilot's body: (speaking to Sam) I know what happened to your girlfriend! She must have died screaming! Even now, she's burning!
Dean: This is going to sound nuts, but we just don't have time for "The Truth Is Out There" speech right now...
Dean: Sam, this plane is going to crash, okay? So quit treating me like I'm freakin' four!
Sam: You need to calm down.
Dean: Well, I'm sorry, I can't!
Sam: Yes, you can.
Dean: Dude, stow the touchy-feely, self-help-yoga crap. It's not helping!
(Dean is being fidgety on the plane)
Sam: Just try to relax.
Dean: (through clenched teeth) Just try to shut up!
Sam: Are you okay?
Dean: No, not really.
Sam: Why? What's wrong?
Dean: Uh, I kind of have this problem with...
(moves his hand in a plane motion)
Dean: It's never really been an issue until now.
Sam: You're joking, right?
Dean: Do I look like I'm joking?!? Why do you think I drive everywhere, Sam?!
Sam: Never? You're never afraid?
Dean: No, not really. (Sam pulls a long knife out from under Dean's pillow) That's not fear. That's precaution.
Dean: When's the last time you got a good night sleep?
Sam: I don't know. A little while I guess. It's not a big deal.
Dean: Yeah, it is!
Sam: Look I appreciate your concern...
Dean: Oh, I'm not concerned about you. It's your job to keep my ass alive! So I need you sharp.
Dean: Did you get any sleep last night?
Sam: Yeah, I got a couple of hours.
Dean: You're a liar. See, I was up at 3 and you were watching the George Foreman infomercial.
Sam: What can I say, it's riveting TV.
Sam: If she's possessed, she'll flinch at the name of God.
Dean: Uh, nice.
Sam: Say it In Latin.
Dean: I know!
Sam: Uh, in Latin it's "Cristo."
Dean: Dude, I know! I'm not idiot!
Sam: You humming Metallica?
Dean: Calms me down.
Dean: I look like one of the Blues Brothers.
Sam: No you don't . You look more like a seventh grader at his first dance.
According to Supernatural: The Official Companion - Season 1, the EMF meter built by prop master Chris Cooper was actually made out of a real Walkman, as Dean states in the episode.

"A Day in the Life of Jensen and Jared", featured in Season 2's bonus features on the boxset, shows both actors going into the trailer to record the commentary for this episode. Jared Padalecki jokingly points out that it was filmed about six months previously, something which made a detailed commentary difficult.
This was the last episode aired in The Netherlands.
Jared Padelecki and Jensen Ackles do the commentary on this episode for the Season 1 DVD.
The airport terminal where Sam and Dean are boarding the flight to exorcise the demon, is actually the terminal Jared and Jensen fly out of when they go back to Los Angeles.
