The ship shakes violently, emitting a metallic twisting sound before starting to nose-dive toward the island's dense jungle. Panic is absolute inside the cockpit. While Tony tries to stabilize the controls and Fury shouts orders, you instinctively grab onto whatever is near: your father's arm, and, in your desperation born from a fear of heights, you end up clutching the tunic of Loki, who is chained nearby. He stares at you with a grimace of disgust, trying to shake you off as the ship roars while it plunges.
