It actually says to set waypoint 4 which is inline with the target but I keep going straight, on autopilot. I will steer myself that way. But, having given up on that one for a while, I went back to the Maverick Tutorial and actually, finally nailed the first tank. Unfortunately the next instruction for this one is to come around, fly out over the water for a few miles and set up for the next Mav. As I peel off the seeker head stays on target and swings to its gimbal limit. And nothing I do works from there. Guess I'll just try, try again.
