Factual error: Hot Air Balloon's have no lateral control. They fly in the direction the wind is blowing, so it's rather impossible for two hot air balloon's very close to each other to be flying in different directions, let alone fly exactly to the desired locations.
Factual error: The Joes chase Cobra into the snowy mountains and attack inside the weird cave. One of the Joe's vehicles splits to a driving section, and Road Block flying up in a little fighter. Road Block is holding a large rifle with both hands, yet the fighter goes up and turns around and begins flying at his control but he never touches a steering wheel or anything. Just his big gun. And he does not speak so no voice commands are given. How is he flying with no hands? (00:19:40)
