April 2018 marks the centenary of the founding of the RAF. In a 90 minute documentary Colin and Ewan McGregor explore the first hundred years of service.

This programme explores the heroic, adventurous and often moving stories of airmen and women who were part of these key moment in the world's first independent air force.

The film follows a series of missions that the brothers undertake. For each mission the McGregor's will be flying in the aircraft that defined a moment in the RAF's history from a WW1 biplane to the latest supersonic fighter. In each case they will be mentored and coached by the expert pilots who fly these rare and expensive aircraft for a living. As a finale the brothers take the controls of a Typhoon worth 60 million pounds, flying faster than the speed of sound.

All profits from the sale of official RAF100 products will be made to the RAF100 Appeal.
