Crossroads of the World

S1 E4: 700 flights from 5 continents land at Frankfurt Airport every day, a feat only possible due to specialists from 70 countries working together to welcome passengers into this busy hub. Meet the teams that connect this Mega Airport to the globe. We show how over 20,000 weird and wonderful ground vehicles race across the tarmac to keep flights on schedule, how retail specialists have turned international shopping into a science, and how a four-legged fleet of sniffer dogs are leading the fight against global drug smuggling.
