Clearly this is my favorite of the trio. The opening "Thunderbirds" inspired scene alone shows an Englishman remembering his roots, thank you for that. The chase scene is one of the funniest made in animation, I can only think of the Norwegian "PINCHCLIFFE GRAND PRIX" to match it (If you haven't seen that movie, do it!!)
