NBC News: A former Air Force drone operator who says he participated in missions that killed more than 1,600 people remembers watching one of the first victims bleed to death.

Brandon Bryant says he was sitting in a chair at a Nevada Air Force base operating the camera when his team fired two missiles from their drone at three men walking down a road halfway around the world in Afghanistan. The missiles hit all three targets, and Bryant says he could see the aftermath on his computer screen – including thermal images of a growing puddle of hot blood.
