That said, there are issues with the entire Slipspace note, anyway.
For starters, Slipstream Space is highly radiated, to the point where much of the mass of a slip-capable ship has to be lead, to absorb and deflect radiation for extended periods. (Beyond real-space cosmic ray deflection capabilities) The sheer amount of radiation would have ripped through even a sealed MJOLNIR armor, to say nothing of Jorge's compromised armor.
Under the assumption he could somehow survive the radiation, Slipstream Space is very turbulent. In canon, it's given that a Covenant Spirit dropship had to be braced and retrofitted with as much armor as they could spare, and even that came near being destroyed when it dropped out of a vessel in-slip. From what we know about Covenant materials, their metals are far more rigid than any known human metal, and such a dropship can absorb more damage than even the MJOLNIR battlearmor. Even if he could have survived the radiation, he'd be killed by the turbulence of the stream.
But, past that, let's look at another interesting issue: it was an uncontrolled Slipspace rupture that enveloped the ship. While controlled ruptures of Slipspace are benign to ships designed to handle the stream, the ship's navigation computer has to manage the quantum filaments of the stream and flow along the right threads of space to stay intact and follow the right course, then at the exact right moment, drop out of the stream by rupturing it again. In canon, that secondary maneuver has been shown to cause massive distance errors, based on nanoseconds of delay between ships. In canon, it is also stated that when a slipspace drive destabilizes in-slip, the nav-com shuts it down, drops the ship from Slipspace, and sends a distress signal. (STP - Slip Termination- Preventable) But, given that the rupture was uncontrolled, everything was enveloped in a random filament of Slipspace. Possibly, more than one filament. At the atomic level, the ship was ripped apart, for sure at least around the edges of the rupture. Based on the above properties, it is reasonable to assume that matter inside would be broken down at the atomic level, as well.
But, even if we can assume all of that isn't true, there still remains the canon issue that engineers working on operating Slipspace drives have been known to disappear from existence, apparently transported into the stream, unprotected. In that case, Jorge would be similarly flung on his own, apart from the ship and its contents, and would have died, even if he was thrown out of Slipspace, unscathed, because his armor was compromised. Even if that didn't happen, the drive's energy would have caused sufficient force to kill him as it created the rupture, unprotected. Even if that didn't happen, the force would have exploded the Pelican, and the explosion would have killed him.
When In Amber Clad and the Assault Carrier slipped, the finely-controlled rupture (Which are far less energetic, therefore causing less damage, according to canon) caused several buildings, as well as the frigate to be pulled into the stream, in piggyback. Some of those buildings survived, somewhat intact, but keep in mind their structures were made of thick, radiation-resistant concrete, and they were large constructs, in comparison to a human. (Note how they size up compared to the 470-meter-long frigate) This happened under fairly ideal conditions and still caused that much damage. (The only reason in-atmo jumps cause so much damage is because the rupture emits a large quantity of energy into the area around it. In-atmo, there's a medium through which it can travel. Note the rupture didn't seem much larger in size than a CAC would have needed in space, but rather, the energy was released upon collapse, when the radiation surged through the air.
Even assuming that ship is a Frigate, on Reach's surface, Reclaimer's right. The only bit that could be is a midsection. Chief was trapped in the aft, and the midsection was with the Arbiter. There is physically no way that could have been the same vessel the Master Chief boarded at the end of the Battle of the Ark. Furthermore, you can't argue that planet is Reach. The Reach we see is scarred by being glassed. Even still, the planet seems to be organic, and covered in natural material. Forerunner planet from Halo 3 has Forerunner design design elements, and seems to allude more to Onyx than Reach.
While I'm all fine to speculate things we can't be sure of, I don't see how you can argue in any way that Jorge survived, or that Reach is the Forerunner planet seen at the end of Halo 3. Spartans never officially go KIA, but let's be honest. They do die. I mean, is Sam still alive? So, let me hammer off my list of debunks before I go:
Jorge- See the whole post
Kat - The needle rifle round completely penetrated her skull, exiting on the bottom side. Rounds are of sufficient size, and was placed in correct area to remove enough brain matter to cause systemic shock and end life function.
Carter - He was mortally wounded during the flight from Sword Base to Aszod. Upon Noble encountering a Scarab, he attacked at full speed and crashed the Pelican into the Covenant walker, killing him.
Emile - Covenant energy sword position appears to have penetrated his lungs and possibly his heart. Damage appears to run to the spinal cord. Even if he could have survived the loss of his lungs, blood loss would have killed him imminently.
Jun - While it's possible you can argue he survives, and he does survive the game, an as-yet unnamed Spartan is stated to have been killed, defending Halsey, as she escaped Reach, in one of the novels. (I believe Fall of Reach. (Which is canon, according to Bungie, and takes place parallel to the events of Halo: Reach. Both serve two perspectives of the battle))
Six - I swear, if you don't accept that one, I'm gonna rip you, your mother, and your youngest sister a new one.
