Ref @Drum_God’s contention two posts up, as wisely replied to by @TokyoBayer just above.
I flew fighters for USAF in the 1980s. In survival school we addressed a lot of self first-aid situations. Because damn near nobody survives an ejection uninjured. Broken limbs, eye damage, big lacerations, etc. Depending on how your aircraft was hit, shrapnel wounds and major league burns are also not uncommon.
We also addressed sneaking around in the countryside living off the land for weeks / months until rescued or somehow making it back to friendly territory. But that part had a distinct air of fantasy attached to it. The half-life of your life was reckoned to be about 2 days. Assuming you didn’t land on an ice floe, the middle of an ocean, or way out in a shadeless, waterless, foodless desert. In which case your half-life was about 6 hours. Unless seriously injured. Etc.
Back in e.g. WWII they didn’t have high speed ejection injuries, but they did have the difficulty of manually bailing out of a burning flailing bomber or fighter. Getting to the exit, opening it, and jumping out under conditions with lots of fire and centrifugal force is a non-trivial problem. Also while not colliding with the e.g tail of your aircraft before you achieve separation. Ejection seats were invented in the 1950s to solve these other severe problems, but brought plenty of their own. As does 500 or 1000 knots of windblast as aircraft speed increased with the transition from props to jets.
So now you’re on the ground and a 1%er who’s happily uninjured. You’re dressed like an enemy aviator, your ethnicity is that of the enemy, you probably don’t speak the local language at all, or if you do you sound like a foreign tourist from the pre-war era.
Good luck surviving your first encounter with a local. Since guys like you killed their brother or parents, your remaining time on Earth is quite likely to be (in the immortal words of Hobbes) nasty, brutish, and short. Avoiding all contact with local civilians was drummed into us as essential to survival. Just as much as avoiding encountering an enemy platoon of soldiers, and maybe more. Soldiers might abide by Geneva Convention standards on prisoner treatment. Civilians are under no such obligations. If they even knew they existed.
While I was in USAF, most of my / our senior officers / aviators were Viet Nam veterans. To a man they were quite convinced that many fliers had survived to the ground, been killed by the locals, and that the North Vietnamese government was telling the truth that they had no record of anybody parachuting down near Village X on date Y. The villagers made sure nobody knew what they’d done. The rest merely succumbed to their injuries alone in the uninhabited jungle, be that an hour later or two weeks later.
