I fail to see why it has to be this specific. I might approach this by stating that 3931 is placed in an "enlarged" space, similar to what 082 did.

When D-series subjects
D-Class.
When D-series subjects initially entered SCP - 3931, they noticed a faint odor of blood, though none could be chemically detected inside the cabin. One subject, who was sitting directly facing the holes in the cargo hold was killed after 15-20 of similarly-sized holes formed in his abdomen. Autopsies remain inconclusive, as the holes appear to be cut and cauterized at the molecular level. From time to time, SCP – 3931 starts its engines, despite a lack of fuel present in the tanks. This proved hazardous when a D-series subject was killed by the spinning blades. During both incidents, the personnel involved were both of Russian and Vietnamese military background, respectively. SCP – 3931 has also been observed raising and lowering flaps, as if trying to take off.
This is written like a post-experiment report but is placed in the description. I suggest rewriting this part entirely by removing the mentioning of specific subjects.
It was quickly shipped to the SCP facility for containment.
Saying this makes it feel like there is only 1 site for containment of everything that the Foundation contains. Also, it's the Foundation, not the SCP Group or SCP Containment. Only the Foundation. A possible rewrite would be "It was contained within Site-202" or "It was placed under Foundation custody"

Don't use too many adjectives. Use them when they help containment, and avoid them when it only makes it easier to imagine the thing.
1: Damn, they said that we'd be out of here, maybe 3 weeks ago? What's going on?
2: Are you complaining? We've got, like, the easiest job. Or, safest, I should say, [inaudible]. We get to sit here all day in this lovely, lovely aircraft.
3: Copy that.
1: Copy that.
1: Hey, [inaudible], comfy?
*no response is heard*
3: I think he's asleep.
2: Shouldn't be. We're on approach, I'll go wake him.
*Bumping sound, presumably 2 leaving their seat*
1: She flies way better now, without the thirteen guns and the flares on board.
3: Can you explain to me again, why we have none?
1: Well, you know those big new planes, the C-130s?
3: Yeah?
1: They're starting to convert them into gunships now. I understand why. Way faster, and four engines are better for when one gets shot. Also have way more firepower.
3: That right? So I suppose these are just for cargo duty now?
1: Yep. Actually, they're decommissioning this one next may. I'll miss her, sure will.
*Slow walking, assumed to be 2 returning to the cockpit.*
2: I got him up. How long till we reach the strip?
1: 'Bout a minu…
*1 is interrupted by 3*
3: Guys, we got an unidentified craft, south, 7-o-clock!*
2: Probably one of ours.
1: Wouldn't surprise me.
*A low frequency 'boom' can be vaguely heard. This is assumed to be the sonic boom from a fighter jet.*
2: Fuck me. That's a mig…
*The engines can be heard speeding up, and wind noise increases. This is likely the pilot's attempt at evasive maneuvers.*
*A distant rumble can be heard, following by metallic dings. The rest of the tape records almost complete silence. Strong wind noise can be heard, and the plane's altitude warnings sound.*
