Please someone explains... (spoilers)
I've just watched this movie again, and once again, I fail to figure when and how Al managed to sneak back inside a plane darting straight to the Gate, from his frail and falling piece of wing (how do they even make a safe landing on this?). Unless he set up beforehand some alchemical teleportation pod inside the suit (that would be a first), and even so it would have been one hell of forethinking...
I'm actually much less bothered by the Elric bros leaving Amestris for ever (though I really feel sorry for Winry), than by this lousy "hello! got on board at the last minute!" trick.
