 FACT: The general states that the ailerons are jammed by Johns  coat. However, the moving panel John puts his coat under is one of  the spoilers. The aileron is located far more to the tip of the  wing. Also even though flight spoilers are used to aid steering the  plane in flight by assisting the aileron, the General would still be  able to move his controls unaffected and a turn to the left would  have lifted the spoiler on the left wing, freeing Johns coat.
