"INTO ACTION. As Yankee Papa 13 approaches the landing zone, Farley opens fire (above) with his M-60 machine gun at Vietcong positions. Burrows took this picture with a camera mounted outside the copter on a special rig attached to the gun. As the gun swiveled, so did the rig, thus keeping the camera always pointed directly at Farley. Burrows triggered the camera by remote cable while squatting out of sight behind Farley."

Image 12/29 of the photos of Larry Burrow's 'One Ride with Yankee Papa 13'.
