Royal Caribbean's Oasis of the Seas left the STX Europe yard at Turku (Finland) this week on sea trials.
Flying above the 220,000-ton vessel is the aerostat (a type of tethered balloon) which RCCL chairman Richard Fain talked about recently. It's an experiment of an additional feature for Oasis, which he said he gives less than a 50% chance of actually being implemented. He will neither confirm nor deny the rumors about the use the company would have for the aerostat.
