A LOT Polish Airlines SA Dreamliner flying to Warsaw from Toronto made an unscheduled landing in Iceland due to a problem with the aircraft's onboard identification system. The Boeing Co. 787 aircraft landed at the Keflavik airport after Norway denied permission to fly over its airspace because of the faulty system, LOT spokeswoman Barbara Pijanowska-Kuras said by phone today. The identification system sends out information about a plane to air-traffic control staff and helps identify the aircraft in the air. The Polish airline sent two planes to Iceland to transport the passengers, she said.
