MOSCOW — In other countries, you may be asked to give a push to a car stuck in the mud. In Russia, passengers in the Arctic came out of an airliner to the bitter cold to help it move to the runway. A Russian-made Tu-134 with 74 oil workers and seven crew members onboard was due to fly from the town of Ingarka on Tuesday to Krasnoyarsk 800 miles to the south when the plane’s chassis brakes froze to the ground.
