To celebrate the centenary of the Royal Air Force, Ewan and Colin McGregor take to the skies in some of the world’s most iconic planes. These are the planes that were involved in aerial combat at every stage of the RAF’s story, from the biplanes used in the early days of dogfighting in World War I to the beautiful Spitfire of the Battle of Britain, the plucky Lysander and on to mighty Vulcan nuclear bomber, as well as the Chinook helicopter and supersonic Typhoon that are still in service today. It is a story of amazing machines and epic battles, but above all it is the story of the men and women whose courage and ingenuity have been at the heart of the RAF for 100 years. On their journey Ewan and Colin meet an amazing cast of characters.

As the most dammed, dibbed, and diverted river in the world struggles to support thirty million people and the peace-keeping agreement known as the Colorado River Pact reaches its limits, WATERSHED introduces hope. Can we meet the needs of a growing population in the face of rising temperatures and lower rainfall in an already arid land? Can we find harmony amongst the competing interests of cities, agriculture, industry, recreation, wildlife, and indigenous communities with rights to the water? Sweeping through seven U.S. and two Mexican states, the Colorado River is a lifeline to expanding populations and booming urban centers that demand water for drinking, sanitation and energy generation. And with 70% of the rivers’ water supporting agriculture, the river already runs dry before it reaches its natural end at the Gulf of California. Unless action is taken, the river will continue its retreat – a potentially catastrophic scenario for the millions who depend on it.
