But when the men of 3 Para get pinned down during Op Mutay, the Army's reservations about their fearsome new fliers are thrown out the window. In the blistering firefight that follows, Ed fires the first ever Hellfire missile and, with one squeeze of the trigger, changes the war in Afghanistan forever. What had been looking like a £4.2 billion mistake quickly becomes the British Army's greatest asset, as the awe-inspiring Apache is dramatically redirected to fight the enemy head on.

In this gripping account of war on the ground and in the skies above the dusty wastes of Helmand, Ed recounts the intense months that followed: the steep learning curve, the relentless missions, the evolving enemy and the changing Rules of Engagement. As he comes to grip with the Apache, his early career as a paratrooper stands him in good stead, as does his operational baptism as a pilot. Both shaped his ability to fly, fight and survive during that fateful first Afghanistan tour against a cunning and ruthless enemy.

Ed will need every ounce of willpower and skill to succeed over the long, hot Helmand summer, as he and his colleagues find themselves on trial for their lives and for the reputation of a machine on which the British government had staked a fortune. The crucible of fire that awaited them would cement the fate of man and machine forever.
