Safety announcements feature on every commercial flight, but Air New Zealand have gone a step further by offering "safety tips" to Ireland rugby fans ahead of their quarter-final with the All Blacks on Saturday. New Zealand, the defending world champions, have been keen to play down their favourites tag against an Irish side they have lost to in two of their past three meetings. However, the national airline has had no such qualms in teasing Saturday's opponents, urging Ireland fans to brace for impact. In a made-to-go-viral online ad, "flight attendants" give a safety briefing in a house occupied by an increasingly forlorn trio of Irish supporters, telling them "to lean forward into the crouch position with your head in your hands" in the event of an early New Zealand try. New Zealand are favourites to win the clash and go on to lift the Webb Ellis Cup for an unprecedented third successive time. But the southern hemisphere side has struggled in recent head-to-head games with the Irish. "Having won two out of the last three games, some Irish supporters may be expecting a pleasant journey," the faux flight attendants say. "However, we happen to think you might be in for some upcoming turbulence. "Should the game go down to the wire, an oxygen mask will automatically drop down. Otherwise, please remain seated until your disappointment has come to a complete halt." The winner of Saturday's match will take on either England or Australia for a place in the Rugby World Cup final.
