No worries. Yeah, you'd think he'd be able to. I find there's a lot of questions that arise (in any movie, be it Transformers, Avengers, The Dark Knight, etc.) that sort of make you go "Wait, why didn't so-and-so just do X?" or "Why couldn't they just do Y?". Unanswered questions like that aren't exclusive to poorly made films. Even the best of them suffer from this.
