Food Lab by Ben Milbourne

A couple dream of a waterfront home with a resort style garden. They also dream of both jobs finishing at the same time. They've green lit work on the garden while the house is still under construction. A good idea, in theory.

For explorers, the means to go into the mysterious depths of the world beneath the waves had always remained a dream. For military strategists it held a particularly pressing fascination. This programme tells how the submariners' vessel was developed, from the erratic experimentation of the early days up to the triumphant diving and surfacing of the modern submarine.

We follow the extraordinary 8000km, 13-day journey across six countries that it takes to get a packet of smoked salmon to the dinner table. We find out how international shipping is helping an unlikely entrepreneur making vodka in the notorious South African township of Soweto go global. At East Midlands Airport in the UK, we get behind the scenes of the big sort and find out how each night they can handle 47,000 packages an hour, and get them on the right planes and trucks for the next stage of their delivery.
