In 1918, the RAF was established as the world's first independent air force. To mark the 100th anniversary of its creation, Penguin are publishing the Centenary Collection, a series of six classic books highlighting the skill, heroism esprit de corps that have characterised the Royal Air Force throughout its first century.

The gripping true story of a Royal Marine helicopter pilot on exchange with the RAF. Major Mark Hammond was awarded the DFC for remarkable feats in Afghanistan in his Chinook helicopter. Like the other Chinook pilots and crews, and the surgical teams who travelled with them, Hammond regularly put his own life in danger to save the lives of others.

Three times on the night of 6 September 2006 he flew into hostile zones to pick up injured soldiers. During an attempt to land at the Para outpost in Musa Qala two rocket-propelled grenades passed within 10ft of his helicopter and four rounds hit it. Forced to abort the mission, he returned to Camp Bastion, found a new Chinook and flew back into battle, rescuing a soldier while still under heavy fire.

Immediate Response is Major Mark Hammond's highly personal account of combat and provides readers with a vivid account of the brutal realities of war.
