A single moment of hesitation changed everything. Instead of Curly running into the cockpit and getting burned to a crisp, he hesitates for just a moment, shocked and furious at the actions of his co-pilot, and the ship crashes just as Curly is about to open the cockpit door.
Curly still gets injured, mind you - layers of skin on his face getting destroyed, affected vision, and, most notably, his left arm getting completely destroyed and ending up being amputated. Not an ideal situation, but hey, it could always be worse.
So, while Curly still has mobility, he is able to experience the effects of the crash right next to everyone else. He isn't confined to a bed, he can see everything first-hand and can openly talk about it, too. Will the reliable Captain Curly affect how the story unfolds?
(also little author's note I headcanon Curly to be Scottish so expect some Scottish-sounding dialogue when he speaks)
