Teal'c and Colonel Jack O'Neill test a Death Glider they acquired from Apophis in the past. However, the Glider has a life of its own, when a Recall device installed by Apophis sends the ship back to Chulak, which will take several hundred years at their current speed, and they only have a few days of oxygen.
Teal'c is test-flying the X-301 Interceptor, an experimental United States Air Force fighter assembled from parts of two of Apophis' Death Gliders (recovered after Apophis' attack on Earth) and human tech. It can achieve Plantilla:WPS with virtually no Plantilla:WPSs for the pilots, and even Carter doesn't fully understand how it works. Lt. General Maurice Vidrine is impressed (though not as much by O'Neill's sense of humor.)
The next test is aerial combat, with the SGC serving as Plantilla:WPS. Colonel Jack O'Neill joins Teal'c in the X-301, but they overshoot the attack run, heading directly out into space. "We are no longer in control of the vehicle. I repeat, we have lost control and cannot eject. Please advise."
Once they're moving at a million miles an hour through space, propulsion shuts down. Apophis' recorded voice states that he installed booby traps (aka Recall devices) in his gliders, so none of his betrayers would be able to use his craft, and they would return to his homeworld...after a very long time.
Affected by the time lag it takes for radio signals to reach the X-301, Major Samantha Carter and Major Paul Davis at the SGC - with O'Neill and Teal'c on the glider - collaborate on a plan to slingshot them around Jupiter: The rocket motors of the AIM 120A air-to-air missiles, never fired during the weapons test, are still under their control. Unfortunately, the missiles don't have enough thrust and one breaks away from its mounting, hits the glider causing some damage, forcing O'Neill and Teal'c to reduce life support to freezing temperatures and very low oxygen levels.
Dr. Daniel Jackson contacted allies capable of spaceflight. Anise of the Tok'ra throws him a secret bone by saying she will not risk exposing a covert operative on a Goa'uld-occupied world, even though a Tel'tak is within a day or so of Earth. Carter pinpoints the world, she and Daniel 'gate there and are picked up by Transportation rings. Fortunately, it is the Tok'ra operative, Jacob Carter, who quickly reigns in his temper (he was preparing to destroy part of the planet) once he realizes his friends' lives are at stake. The ship will reach the X-301 in roughly 24 hours.
With 12 hours of air remaining, Teal'c decides to go into an extremely deep state of kelno'reem, slowing his heart rate, reducing his oxygen consumption. O'Neill asks who he'll talk to. Teal'c renders O'Neill speechless with his depth of feeling and friendship.
Jacob pushes the cargo ship beyond maximum safe velocity, resulting in the hyperspace engines crashing within spitting distance of two Ha'taks. Daniel stalls them by saying he's the Great and Powerful Oz in Goa'uld. They launch gliders in response, but Jacob and Carter repair the engines and the ship is able to re-enter hyperspace.
Upon arrival, Teal'c and O'Neill are asleep, near death. Jacob nudges the X-301 with the cargo ship, waking O'Neill into an amusing but dangerous daze from Plantilla:WPS. Fortunately, he understands enough to wake Teal'c up by throwing a pen at him. Obeying Carter's instructions, they saturate their lungs with the remaining oxygen, open the glider's canopy, exhale and push away. Five meters from the glider, Jacob rings them aboard. They're both alive.

Vidrine: Light that candle boys.
(walking toward the X-301)
Teal'c: Does General Vidrine wish us to perform some sort of candle burning ritual?
O'Neill: Yes... that's it... exactly.
(Directly after the X-301 had entered space)
O'Neill: Uh, Teal'c, on our six, is that what I think it is?
Teal'c: If you think it is Earth; yes.
O'Neill: It's shrinking.
Teal'c: Its size remains constant, rather it is we who are moving away at extreme velocity.
(A sound comes from the instruments)
Teal'c: These instruments indicate drive shutdown. We're no longer accelerating.
O'Neill: That's good.
Teal'c: I will attempt to restart.
(Suddenly a voice is heard from the machine)
Voice: Shol'va! To all those who turn against their god, know this: For your insolence you will die in the cold of space. What is rightfully mine will now return to me.
O'Neill: Was that who I think it was? And did he just say what I think he said?
Teal'c: If you think it was Apophis, and that he said that the gliders from which this craft was constructed contained a device designed to return this glider to his homeworld, then yes.
O'Neill: He also mentioned something about dying.
Teal'c: In the cold of space.
O'Neill: Now the old boy hasn't lost his touch, has he?
Jacob: So how do you intend to get them out of the glider once we get there? I mean, there's no chance it'll fit into the cargo bay.
Jackson: Well, we were kinda hoping that you could... um, like... beam them out or...
Jacob: (laughs) Beam them out? What am I? Scotty?
(A Jaffa aboard one of the Ha'taks contacts Jacob's ship)
Jaffa: Kree tal shal mak, Heru'ur!!
Jackson: Mak tal shree, lok tak mekta satak Oz!! (the radio repeats him in a Goa'uld voice)
Jaffa: Mak tal Oz!?
Jackson: Mak tal Oz kree!! (the radio repeats him in a Goa'uld voice)
Jaffa: Kal tak shree tal ma nak!!
Jacob: All right, we're almost finished, Sam's just finishing.
Jackson: Uh, that's good, cuz I don't think they bought my act.
Jacob: Why, who'd you say you were?
Jackson: The, uh... Great and Powerful Oz.
Jacob: (eye roll, sigh)
O'Neill: Jacob, is that you?
Jacob: Yes, it is, Jack. Now do what we tell you.
O'Neill: Do you know your ship's bigger than ours?
- While the X-301 Interceptor is not seen again (which is most likely a good thing considering the events of this episode), Colonel Jack O'Neill remembers it vividly in "Fail Safe" and "Redemption, Part 1".
- The Great and Powerful Oz is one of Stargate SG-1's many references to The Wizard of Oz. According to producer Brad Wright, Robert C. Cooper wrote an Oz reference in an early script, and especially with Richard Dean Anderson's tendency to ad-lib, it grew from there.
- At the end of the episode, Teal'c and O'Neill are briefly exposed to vacuum without space suits. This will probably be survivable as long as they are re-compressed quickly, which (in the episode) they are. However, they are seen keeping their eyes open which would not be advisable in a vacuum. 
- The missiles the X-301 has are equipped with shield frequency modulators which theoretically should enable the missiles to pass through Goa'uld shields. However, this is never brought up again in the series, meaning that it was merely an experiment and perhaps failed when put into actual use.
- While it was a failed experiment, the X-301 featured in this episode was the first step towards Earth developing its stellar fleet; the X-301 concept later evolved into the entirely man-made X-302 hyperspace fighter, as well as the X-303 cruisers, most famously represented by the flagship Prometheus.
- There is an allusion to Star Trek: Dr. Daniel Jackson says to Jacob Carter: "We were hoping you could beam them out." to which Jacob replies, "What, who am I? Scotty?"
- When Major Samantha Carter tells her father Jacob to "Punch it" before jumping to hyperspace, this is a reference to Star Wars in which Han Solo tells his Wookiee co-pilot to "Punch It" before jumping to hyperspace. She also says the same line to Teal'c in "The Serpent's Lair".
- O'Neill refers to not wanting to freeze to death again, probably in reference to "Solitudes."
- The planet where Jackson and Carter are headed to inform the Tok'ra (P2C-257) looks a lot like the planet from "Need" (Terella).
- The plot of this episode is reminiscent of the Plantilla:WPS mission.
- This is the only episode of Stargate SG-1 written by Michael Cassutt.
- Steven Williams (Lt. General Maurice Vidrine) previously played Capt. Adam Fulleron alongside Peter DeLuise on Plantilla:WPS and Mr. X in The X-Files.
- The initial pass of the X-301 Interceptor is announced as coming from the southwest, yet the camera looks along Runway 18 (South) to see it approaching.
- Southwest is still technically South. It is a considerably large flight craft so just facing in the overall general direction should be enough to see the massive craft coming.
- According to Air Force regulations, Lt. General Maurice Vidrine's mustache would not be allowed. To be within regulation, it would have to end at the corner of his mouth.
- Teal'c remarks that the X-301 will take several hundred years to reach Apophis' homeworld as it is traveling at sublight speeds. If the ship is indeed traveling at a slow (in interstellar terms) 1,000,000 mi/h the trip to even the nearest star (Plantilla:WPS) would take about 2700 years. Presumably Apophis' homeworld is far more distant. Also traveling at 1,000,000mph, the trip to Jupiter would have taken the X-301 two weeks. However, Teal'c also mentioned that when the drive shutdown, they stopped accelaration, implying that the X-301 could have gone much faster. If this was the case, the recall device would have made the drive reactivate at full speed after some time, making trip shorter by an unknown degree. It is doubtful Teal'c would have known exact details though.
