Antonov 124

S1 E3: The Antonov 124, one of the biggest cargo planes in the world, is on its way to earthquake-ravaged Chile to deliver a massive wind turbine. But before this mighty plane can come to the country's aid, it must first prove it can handle the assignment. Witness the obstacles the Antonov and its crew must overcome to complete this two-day, 7,500-mile mission, including extreme weather and an exhaustive inspection that could reveal flaws too costly to repair. For this massive plane, a pit stop could mean the end of the road and an incomplete mission.
