Before Samsung took over as the most prominent advertiser at Heathrow's Terminal 5, it was Nokia that used to occupy the big billboards inside the home of British Airways. Unwilling to hand over the advertising crown with grace, the company now operating under the Microsoft Devices banner has decided to troll Samsung's ads by sending out a set of four "Lumianauts" in search of a flight out into the Galaxy. Describing their apparent disappointment at not finding anything extraordinary at the terminal, Microsoft concludes that at least "the Lumia we have in our pockets is always out of this world."
