I pasted the details of that downed colonel into chatgpt and told it to assess my movie plot, this is that it said
As a military-survival movie premise, it has a strong core, but there’s one giant realism bottleneck: the fall.
The aircraft shoot-down, failed parachute, evasion, injuries, beacon/comms, and eventual rescue all fit comfortably into a military survival story. What strains credibility is surviving an essentially unarrested 70–100 mph ground impact and then retaining enough functional mobility to hike and climb a 7,000-foot ridge. Those are individually extraordinary events; combining them makes the character feel superhuman unless the circumstances of the impact do a lot of work for you.
What works especially well
The failed parachute is fantastic dramatically because it creates a very clean escalation:
Aircraft hit → eject → relief → looks up → no canopy.
That moment is cinematic as hell. And the line “When I looked up and saw no parachute…” works because pilots and aircrew are trained to deal with aircraft emergencies, but once the parachute has completely failed, the character has essentially exhausted the systems designed to save him.
Survival itself isn't impossible. There are documented cases of people surviving enormous falls, including military aircrew. Alan Magee famously survived a fall of thousands of metres after crashing through a railway-station skylight. Nicholas Alkemade survived roughly 18,000 feet after falling into snow and trees.
Those cases illustrate the important distinction: surviving the fall isn't the unbelievable part. Surviving it in sufficiently good condition to conduct strenuous mountain evasion is.
The injuries are where I'd change things
A "broken back" can mean wildly different things. A stable vertebral fracture without spinal-cord injury could potentially leave someone ambulatory. A major unstable spinal fracture or cord injury obviously changes the story completely.
Likewise, "broken bones" isn't specific enough. Broken ribs, fingers, nose, facial bones, or a relatively stable vertebral compression fracture are compatible with somebody still being capable of desperate movement. A shattered pelvis, femur, tibia or serious ankle fracture probably ends your ridge-climbing sequence.
Interestingly, the sprained ankle could become one of the most believable little details. Someone might survive an extraordinary impact through some combination of vegetation, snow, slope and progressive deceleration—and then spend the next several hours discovering that apparently "minor" injuries become agonizing once adrenaline fades.
I'd therefore make his medical picture something like:
Facial lacerations and fractures, concussion, several broken ribs, stable vertebral compression fracture, badly sprained ankle, extensive bruising and soft-tissue trauma.
Now he's catastrophically injured without giving him injuries fundamentally incompatible with what the screenplay subsequently requires.
Don't have him hit flat ground
This is probably the single biggest realism upgrade.
Give him a partial parachute malfunction rather than literally zero aerodynamic braking, or have the failed/entangled canopy produce some drag. Then have him hit something that progressively dissipates energy: steep snow, forest canopy, dense vegetation, a sloping mountainside, etc.
That also lets your character sincerely say:
“I looked up and there was no parachute.”
From his perspective, there isn't a functioning parachute. But investigators can later determine that the tangled canopy probably reduced his speed somewhat.
That tiny distinction buys you an enormous amount of plausibility.
The 7,000-foot ridge needs clarification
If you mean he climbs 7,000 vertical feet after impact, that's actually the element I'd find hardest to swallow after his injuries.
If you mean he lands somewhere on a 7,000-foot-elevation ridge and has to traverse/climb through it to reach extraction terrain, that's much easier to believe.
Even better dramatically: don't make him climb because he's generically Tough Military Guy™. Give him a compelling tactical reason. He landed in a drainage or valley where the surrounding terrain blocks his radio. He knows aircraft are searching for him, but he can't establish contact. He therefore realizes:
If I can get onto that ridgeline, I may get line-of-sight communications.
Suddenly the climb isn't action-movie machismo. It's a horrible calculation by an injured professional: staying here may get me captured; climbing may kill me, but it's my best chance of being found.
That's much stronger.
One other detail I'd tweak: "weapon specialist colonel"
A colonel personally flying over hostile territory isn't inherently strange, but his job needs to explain why he's aboard that particular aircraft. If he's simply a senior weapons specialist, audiences with military knowledge may wonder why somebody of his rank and specialty is exposing himself to MANPADS territory.
Easy fix: make him a weapons systems officer / combat aviator who has subsequently become a senior weapons or tactics specialist, and establish that he's flying an operational evaluation, familiarization, mission-command, or specialist sortie. Then his rank and expertise actually enhance the story.
It also gives you a nice character advantage after the shoot-down: he's not necessarily a super-soldier. He's an extremely experienced aviator and systems thinker suddenly forced into a ground-survival problem.
And I'd absolutely keep the pistol, radio and beacon. In fact, I'd resist giving him much more. The image of this highly trained colonel limping through hostile mountains with essentially a sidearm, radio and beacon is considerably more compelling than turning him into Rambo.
