No matter how or why, the important thing for orc aircraft is to go down and crash.
What do you think the odds are that he was very young and inexperienced? There have been stories about the lack of experienced orcs to fly combat missions. That’s a bad combination; Soviet planes, young pilots, nazi ideology and nothing to fight for. I hope he packed sunflower seeds in his pockets before entering Ukraine…
Sounds like those seeds would be fully roasted, so alas no sunflowers.
