Visible crew/equipment: When Tom's father stands in his bedroom doorway on the day they are going on holiday to tell him that breakfast is ready there is a shadow of the mike on the wall above him.
Continuity mistake: During the scenes at the airfield early in the film the sky changes between shots from blue to grey.
Revealing mistake: When the sky bike is flying during the competition it is obviously suspended from a crane as you can see the wires.
