A new film sees three whistleblowers break the silence around the US drone war, in a decision that will change their lives forever.
Directed by Sonia Kennebeck, the documentary 'National Bird' follows the dramatic journey of three people who have spoken out about the US military's use of drones (click here if you'd like to watch our interview with her about the production).
Plagued by guilt over participating in the killing of faceless people in foreign countries, it sees the whistleblowers decide to speak out publicly, despite the possible consequences.
Their stories take dramatic turns, leading one of the protagonists to Afghanistan - where she learns about a horrendous incident. 

Errol Morris, director of The Fog Of War, said:
"National Bird is a one-of-a-kind film... [that] offers an unparalleled glimpse into the surreal landscape of automated murder.
"Who are these people, who sit in windowless rooms and make life-and-death decisions based on blurry images flickering on computer screens?"
"On paper, it’s a seemingly smooth, uncomplicated job. Except there’s a conspicuous lack of moral clarity about who is targeted and why.
"Even if the true identity of the victims is known, National Bird reminds us that we’re living in an electronic haze, where life and death are decided on the basis of, as often as not, caprice.
"Detachment and a lack of accountability are rewarded where responsibility and compassion are shunned."
"For many servicemen, time in service may be little different than a video game gone mad [or come to life]."
