The hard-of-hearing Professor Cuthbert Calculus (from the famous Tintin series) would have been delighted if he knew that Brussles Airlines has chosen his submarine as part of its efforts to be Belgium's ambassador. One of the airlines' A320s have been painted to look like the shark-faced submarine with Tintin and his trusty companion Snowy inside. In partnership with Moulinsart, the company that protects the work of Tintin&rsquos Belgian creator Hergé, Brussels Airlines has introduced this new Tintin-inspired livery. The rear walls of the aircraft have also been painted with pictures of Tintin and Captain Haddock from the story, Red Rackham&rsquos Treasure. The aircraft, dubbed Rackham, completed its maiden flight to Toulouse on March 13. The aircraft in Tintin livery will remain in operation until 2019. Those unfamiliar with the story, can read the comic book on board in Dutch, English and French.
