On a plane at an airport in Vladivostok, Russia, a woman goes into labor. While the plane is taxiing down the runway, her first child is born at 9:00am, January 1st, 2009. The plane flies to Anchorage, Alaska, USA. The flight takes 1 hour, but crosses the International Date Line and therefore touches down at 11:00 am, December 31st, 2008. The woman gives birth to her second child--born after the first, but on in a different, earlier year.
